Hello, I'll be critiquing your homework today.

Your lines look really good! Both confident and accurate, there is only a tiny bit of wobbling in the rough perspective exercise.

Your ellipses are also good. Confident and within bounds, in one of your funnels (the bottom left one) the minor axis doesn't cut the ellipses in half, but the rest are fine.

Boxes are good to go as well. You've drawn through all them, except for the organic perspective (where it was optional anyways), your hatching is confident and clean. One of your boxes (second row from the top, left side) seems to not be rotating, but don't worry you'll be working on that on the 250 boxes challenge. The only slight issue that I see is that you have forgotten to add line weight where lines overlap in the organic perspective exercise.

Overall I would say you did really well.
