Good job on finishing Lesson 1!

Lines

Your ghosted lines exercise has a very slight arc to it, and your ghosted planes exercise overshoots the mark from both directions a lot. Overall, though, this all looks really good.

Ellipses

The ellipses inside the planes have a bit of an accuracy problem, but this problem doesn't seem to carry over to the other ellipses exercises. Try practicing inside planes, otherwise you're pretty good with the rest of the ellipses.

Boxes

The accuracy problem with the lines exercises is still here. Try ghosting a little longer before drawing lines, and see if that helps. Otherwise you seem to have gotten the hang of vanishing points pretty well. The boxes feel very 3-dimensional, that's great.

Overall, you did a good job with everything.
