Printer paper (A4) is highly recommended, here we go.

1. Lines

Superimposed Lines: Good confidence in your lines, but some slight wobble is present along with slight arcing.

Ghosted Lines: (Slight) Wobble and arching is present.

Ghosted Planes: Wobbling is present in some of your lines, don't be afraid, being inaccurate with a straight line is better than being accurate with a wobble-meister. Also, remember to aim for that magic dot at the end.

2. Ellipses

Table of Ellipses: Some ellipses go slightly out of bounds, some ellipses also overlap each other. Most of them also are undershooting the boundaries. Some ellipses wobble here.

Ellipses in Planes: Few ellipses go slightly out of bounds and some are under-bounds. Some ellipses also wobble here.

Funnels: The minor axis does not split the ellipses evenly with the farthest ellipses. Some are egg-shaped and lopsided. Missing some of the bounds here and there

3. Boxes

Plotted Perspective: The exercise was completed accurately.

Rough Perspective: Same errors as the lines section(s). Also remember that vertical lines are perpendicular to the horizon, and that the horizontal lines are parallel to the horizon, as there are some not adhering to this rule.

Rotated Boxes: On the face of the boxes facing the viewer you keep things consistent, but the back side is a different story, you are not being consistent and the gaps are not consistent, too much guessing is present.

Organic Perspective: Try to keep the 'Y' above 90 degrees so the boxes don't look too distorted (this appears on some of the boxes). The same errors that were present in the lines section are also here.
