Hey Hitomi! Nice work on your homework. Here are my thoughts:

Lines: Excellent work all around. I think the superimposed lines look incredible. I can tell you took great care to keep from fraying lines on both ends, and that is impressive. For ghosted lines and ghosted planes, I think you did well on these exercises. There are some occasions where you wobble, so make sure you are using your shoulder as a pivot. When you practice ghosted planes as a warm up in the future, I would make sure to vary the size of planes and practice with longer or wider planes.

Ellipses: Overall, your ellipses look fantastic. The table of ellipses are great. They look confident. You vary their sizes very well. It seems like you had a lot of fun with this exercise. The ellipses in planes also look great, too. Similar to the ghosted planes, I would warm up by practicing more longer and wider planes so you can have more experience with various sizes of ellipses. The funnels look remarkable as well. I don't see any loose ellipses; the line bisects them well. Plus, they look confident. I think overall, you are really good at the ellipses exercises.

Boxes: The plotted perspective looks fine to me. There are a couple of instances where you missed the back edge of a box. Don't worry about redoing the exercise for this lesson. Just make sure to keep this in mind when you are doing warmups of plotted perspective. Rough perspective shows promise. You are mostly confident in drawing your lines, so I would continue to do that. As you could tell from the red lines, there are some instances where you miss the vanishing point by a wide distance. That's to be expected of this exercise. The goal isn't to be perfect, but to understand perspective a little better as you are moving forward to the 250 box challenge. The same goes for all the box exercises. I think you did well with the rotated boxes and the organic perspective in understanding perspective a little more. One thing I would like to mention is that in organic perspective, I did not see much rotation of the boxes as they tapered off into the distance. It seemed more like they were rocking. As you are doing the 250 box challenge, I challenge you to draw boxes in different orientations. Overall, great work!

All-in-all, I think you did well with lesson one. You are free to move forward to the 250 box challenge. For warmups, continue to focus on confident line strokes, as well as solidifying your understanding of perspective. Some exercises that will do that are ghosted planes, plotted perspective, and rough perspective.
