| Study | Original subject | Look for |
|---|---|---|
| GS01 | Pitcher and apple | Handle gap and overlapping fruit |
| GS02 | Books and pear | Stacked corners and organic outline |
| GS03 | Teapot and cup | Spout, handle and repeated ellipses |
| GS04 | Bottle and bowl | Tall narrow form beside a wide low form |
| GS05 | Vase and flowers | Thin stems beside a closed vessel |
| GS06 | Lamp and notebook | Joined straight edges and a tilted shade |
On every student page, the top reference uses 8 × 6 cells at 12.5 mm per cell, for a 100 × 75 mm illustration. The lower target uses the same number of cells at 17.5 mm, giving 140 × 105 mm. Both length ratios equal 1.4. A point halfway across a reference cell belongs halfway across its matching target cell; row and column locations do not change.
Use the student pack for attempts and keep the completed-reference pack separately. Each pack repeats its individual pages rather than adding more subjects. Compare the outer silhouette first, then two or three internal landmarks and the gaps between them. A hand rendering can differ in line quality while retaining the mapped relationships. The supplied drawings are original stylized studies, with no photographs, identified portrait subjects or copied character art.
The line-reference and value-reference files retain the same structural contours. The value guide uses three neutral gray fills on white paper, with a stated upper-left light direction and shadows extending down-right. These are illustrative blocks rather than a photorealistic light calculation. Follow an overlap in the line sheet before copying its tone in the student frame.
| Watch for | Check instead |
|---|---|
| Placing cast shadows toward the upper left instead of the lower right. | Adjust shadows to fall toward the lower right, consistent with the upper-left light source indicated in the illustrative value blocks. |
| Confusing structural overlaps with accidental lines cutting through foreground objects. | Review the contours carefully to distinguish intentional structural overlaps from accidental lines, ensuring foreground objects remain clearly defined. |
| Using incorrect scaling dimensions for the target paper. | Ensure the target paper is one hundred forty by one hundred five millimeters to maintain the uniform one point four enlargement from the source. |
Print the PDF matching the paper in your printer at Actual size / 100% if you want to retain the millimeter dimensions defined in the file. Turn off Fit and Shrink when those dimensions matter. Uniform resizing preserves relative image proportions and angles but changes physical lengths. Unequal resizing can distort both. SVG editors and browser print dialogs can also change scale, so measure a physical calibration span when the task relies on size.
These files have digital geometry and layout checks. Physical printer testing has not been completed. Complete a student page before comparing the worked answer or reference illustration. A geometric or counting result can be exact, while a hand drawing can vary in its marks and interpretation. The original resources use CC BY 4.0: credit Zumola, link the license and indicate changes.
No, the illustrative value blocks are not photorealistic light simulations or photographs. They are structural guides using three-level grayscale references to help understand form and shadow placement.
Use the answer version which shares the same grays and contours as the student version. Check objects and gaps before applying value to ensure structural accuracy and correct overlap interpretation.
The source image is one hundred by seventy-five millimeters, and the target is one hundred forty by one hundred five millimeters. This results in a uniform one point four enlargement for accurate proportional drawing.

A grid divides the reference into cells, but each cell still contains two kinds of shape: the object and the space around it. Negative-space drawing asks you to copy the enclosed gaps first. For example, the triangular gap between a bottle and a bowl, or the curved sliver inside a pitcher handle, has a definite width and direction. If that gap matches the reference, the surrounding edges usually land in the right place.
Treat the grid as a coordinate frame, not a set of boxes to fill independently. Count cells from a fixed edge, such as the left and top borders, so every measurement has one origin. Keep the same cell proportions on your paper: if the reference cell is square, your drawn cell must be square. A stretched cell changes every angle and gap even when your line quality is good.
Negative space also separates contour work from tone work. Draw the gap outlines first, then add value only after the contours are stable. This prevents shading from hiding a misplaced edge.
Suppose an original reference shows a cup and saucer inside a grid of 4 columns by 3 rows. The reference is 8 cm wide and 6 cm tall, so each cell is 2 cm by 2 cm. You want a drawing 16 cm wide and 12 cm tall. The scale factor is 2, so each drawn cell must be 4 cm by 4 cm. The grid stays 4 by 3; only cell size changes.
Now measure a gap: the space between the cup base and the saucer rim is 1 cm wide at its narrowest in the reference. At scale factor 2, that gap should be 2 cm on your paper. If your drawn gap measures 3 cm, the cup base is probably too high or the saucer rim too low. Check the cell row of each edge before adjusting the curve.
This example is deliberately simple so you can verify it with a ruler. The same reasoning applies to any uniform enlargement: multiply every distance by the same factor, and keep the grid count unchanged.
A useful check is to compare the number of cells an edge crosses. If a contour crosses three cell boundaries in the reference, it should cross three in your drawing when the grid count is unchanged. A contour that crosses four boundaries signals a shifted start point or a changed angle.
Another check is gap closure. Enclosed negative spaces should close cleanly; open spaces, such as the area above a vase, should remain open. If a gap that is closed in the reference appears open in your drawing, an edge has drifted. Mark the drift with a light line rather than erasing repeatedly, so you can see the pattern of error.
Finally, check tone separately. Value shapes can be correct even when a contour is slightly off, and a dark tone can make a small gap look larger. Compare the gap outline before and after shading; if the shape changes, the tone has crossed an edge.
A reference grid is 5 columns by 4 rows, 10 cm wide and 8 cm tall, so each cell is 2 cm by 2 cm. You enlarge to 15 cm wide and 12 cm tall. A gap between a bowl rim and a book edge measures 1.5 cm in the reference. What cell size and gap width should the drawing have?
The scale factor is 15 divided by 10, which equals 1.5. Each drawn cell is 2 cm times 1.5, or 3 cm by 3 cm. The grid remains 5 by 4. The gap should be 1.5 cm times 1.5, or 2.25 cm. If the drawn gap measures about 3 cm, check whether the bowl rim or book edge sits in the wrong cell row before changing the curve.
Measure one cell width and height on your paper. They should match the scale factor applied to the reference cell. Square reference cells must produce square drawn cells.
Treat it as a region bounded by the paper edge or by an imaginary line. Measure its width at fixed rows or columns instead of trying to close it.
Yes, but confirm contours first. Use the gap outlines to check placement, then apply tone shapes inside the confirmed boundaries.
