1. Lines

Superimposed Lines: Instances of fraying on both ends, watch your placement. There is wobble and arcing in your lines. Wobble is fixed through confidence, arcing is fixed with counter-arcing or it can be fixed by plotting the line in your head.

Ghosted Lines: Same issues as mentioned above. Remember to not redo your lines.

Ghosted Planes: Same issues as mentioned above.

2. Ellipses

Table of Ellipses: Under/overshooting your boundaries, and overlapping to boot. Need to work on some more confidence here to get rid of the wobble.

Ellipses in Planes: Same issues as listed above.

Funnels: Misplacement of some ellipses along the minor axis, same issues as mentioned above. These ellipses do look more confident.

3. Boxes

Plotted Perspective: This exercise was completed correctly.

Rough Perspective: Some mishaps not following the vertical/horizontal rule on your lines, watch your wobble.

Rotated Boxes: Good rotation, good corner placement, but the backsides are slightly skewed: see the back of the center box for an example.

Organic Perspective: Same issues as mentioned above, the 250 box challenge will help with your perspective issues.
