1. Lines

Superimposed Lines: Much wobbling on your first page, but the second is much better, but still has some wobbling and arcing present, good placement.

Ghosted Lines: Good placement, teeny bits of arcing.

Ghosted Planes: Slight arcing and even less wobbling, but it is present.

2. Ellipses

Table of Ellipses: Some overlapping as well as undershooting/overshooting your boundaries, a little wobbling, some more confidence would be beneficial for some of your ellipses, but most are what we are looking for here.

Ellipses in Planes: Same issues as as mentioned above.

Funnels: Misplacement of your ellipses here and there, same issues as mentioned above.

3. Boxes

Plotted Perspective: This exercise was completed correctly, nice outlining.

Rough Perspective: Mostly following the horizontal/vertical rule for your lines. Same issues with the lines themselves as mentioned above.

Rotated Boxes: Some issues with box rotation (https://d15v304a6xpq4b.cloudfront.net/lesson_images/d73eea49.jpg)

                                Good corner placement.

Organic Perspective: Same issues mentioned above.
