On the superimposed lines, your lines look very good, but your pen seems like it's running out. On some lines there is some fraying in the middle, but it doesn't seem major.

Your ghosted lines look pretty good. Trajectory and straghtness look good, it's a very good paper.

Your ghosted planes seem okay. There is some wobble, I suggest you to keep in my mind how important drawing from your shoulder is. But it doesn't seem major.

Your ellipses look pretty good overall, they're snug and drawn with confidence. But in funnels exercise, you should've drawn your curves with an object, not freehanded. Other than that, they're centered and snug. Very good work.

In plotted perspective, you should've put the vanishing points very far apart, so that the boxes don't distort too much. I'm not satisfied with that paper, so I'm gonna request a redo of that. Your homeworks look pretty good, you seem very good at drawing. It shouldn't be so hard of a homework for you.

Your rough perspective looks very good. There is some wobble in the boxes, but you can overcome that with some more confidence. It's not much of a deal.

Your rotated boxes look really good. Some boxes seem to be underrotated a little bit, but it looks alright overall.

In the organic perspective, boxes look like copies, especially on the second page. But you'll figure that out in the 250 boxes challenge.

Overall you seem pretty good. You seem like you figured out the technique pretty much. I'm only going to request a revision of plotted perspective, because it's an important exercise to understand perspective. Very good job. Keep up the good work!
