Your homework looks great overall! Your lines look very confident and straight throughout the exercises.

Lines: Try to gain the control to increase accuracy in hitting the endpoints in your lines. Your corners in boxes and planes feather out with all the lines going through and past the corners. Your boxes will look more crisp if you have the lines coming together and ending at the same point. I notice on superimposed lines you have some feathering at both ends, and in ghosted lines sometimes you are missing both the beginning and end points. This could be an indication that you're going too quickly. Make sure to carefully place your pen accurately on the start point when you are ready to make your mark after ghosting.

Ellipses: Overall your ellipses look good, but sometimes they end up a bit squashed. Make sure you are performing the ellipse motion from your shoulder to get the full range of motion in your arm in an effort to get the smooth ellipse motion each time.

Boxes: Though you are rotating your boxes, there is not much variety in shape and orientation. This is fine for this exercise, and you did a good job creating depth in the scene with your boxes. But be sure when you do the 250 box challenge to do a wide variety of boxes. The Y generator from a Drawabox community member will help: https://tasty-tangy-meeting.glitch.me/ Uncomfortable recommends using the generator for no more than the first 100 boxes of the challenge.
