The 30-Minute Still Life with a Bent Table
In a 30-minute timed still-life test, a student draws a cylindrical tin, a rectangular tiffin box and a conical clay lamp on a cloth-covered table. The light comes from a window at the upper left. The drawing shows the tin's top ellipse as a pointed almond; the tiffin box's front face is wider at the back than at the front; the table edge rises to the right although the setup edge is horizontal; and the cast shadows fall to the right. The student has used an HB pencil throughout and erased three times, leaving grey smudges. With 10 minutes left, the invigilator says 'finish the shading'. The student wants to darken the whole background to hide the errors and to outline every object heavily so it 'looks finished'. The student has a 2B and a 6B pencil in the box but has not used them.
1. Diagnose the four errors in terms of ellipse construction, proportion/perspective, horizon and light direction. Which error is most damaging to the drawing as a whole, and why?

The four errors are linked:
- Pointed almond ellipse: the top of a cylinder is a circle seen in perspective, so its ellipse should have smoothly rounded ends and be symmetrical about its long axis. Pointed ends mean the student drew a lens shape, not an ellipse.
- Tiffin box wider at the back: this reverses perspective. In one-point or two-point perspective, receding edges converge; the front face should be the larger one.
- Rising table edge: the setup edge is horizontal, so the drawn edge should stay horizontal at the same eye level. A rising edge tilts the whole spatial envelope.
- Shadows falling right: with light from the upper left, cast shadows should fall to the lower right, but their direction must be consistent with the object's form and the light angle; here the student has not established a single light source.
The table-edge/horizon error is most damaging because it misaligns every object and makes the still life look unstable. The shadow error is also serious because it contradicts the light source, but it can be corrected locally. The ellipse and box errors are object-specific.
2. Give a 10-minute correction plan. State what to fix, in what order, and what to leave alone.

Do not darken the background; that hides errors and destroys the light logic.
Minutes 1–2: table edge. Re-check the edge against the actual horizontal using the pencil or paper edge. Correct it with a light line before erasing the old one. Minutes 3–4: tin ellipse. Redraw the top and bottom ellipses with rounded ends; check that the top ellipse is flatter than the bottom if the eye level is above the tin. Minutes 5–6: tiffin box. Re-establish the front face and make the receding edges converge rather than widen. Minutes 7–8: light. Erase the wrong cast shadows and place them lower right; keep one consistent light source. Minutes 9–10: tonal accents. Use 6B only at contact shadows, the darkest cast shadow and the lamp's interior; use 2B for midtones. Do not heavily outline every object. Use lost-and-found edges instead: stronger where forms overlap, softer where light wraps around.
Leave the smudges if erasing would damage the paper. A slightly grey paper is less harmful than a torn or shiny surface.
3. Explain how to check an ellipse and a horizontal edge without a ruler, and why switching from HB to 2B/6B matters in the last 10 minutes.

Ellipse check: hold the pencil at arm's length and compare the ellipse's width-to-height ratio with the actual tin. Then check symmetry: the top arc and bottom arc should mirror each other, and the left and right ends should be rounded. Look at the negative space between the ellipse and the tin's side; if it pinches to a point, the ellipse is wrong. You can also turn the paper upside down to see the shape afresh.
Horizontal check: align the pencil with the actual table edge and compare it with the drawn edge at arm's length; or use the top edge of the paper as a reference. Do not use a ruler - sighting teaches proportion.
Pencil choice: HB is hard, limited in tonal range and prone to smudging when erased repeatedly. It cannot produce a convincing dark. A 2B gives clean midtones; a 6B gives dense darks at contact points and cast shadows. In the last 10 minutes, the priority is not 'more shading' but correct structure plus three values: light, midtone and dark. A few confident 6B accents will make the drawing read as finished more than a heavy outline.
