Hi. I'll be handling your work, and I hope this helps you improve.

Superimposed lines look pretty confident overall, but there's some wobbling and arching on your longer lines. in your warm-ups consciously arch in the opposite direction to try and make it straighter. fraying is fine on the end

Ghosted lines are confident aswell, accuracy comes over time. I recommend page-wide lines for this exercise while it's in your warm-ups

Ellipses in planes have some repeating lines. Once you put down a mark, even if it's not accurate, pretend it is and move on. A confident line is more important than accuracy. The ellipses themselves are deformed, and you should prioritize confident and smooth ellipses even if they end up out of the boundary.

Onto ellipses

Tables of ellipses have ellipses that are drawn through more than 3 times, keep it to 2 - 3 (2 preferably). Ellipses are packed nicely against each other.

Funnels are nicely done. The minor axis should cut the ellipse into 2 symmetrical halves.

boxes

Plotted perspective shows you understand two-point perspective.

Rough perspective pages are overall pretty good, some of your boxes hit the vp. try to keep the width lines parallel to the horizon line, and the height lines perpendicular to the horizon line.

Rotated boxes look fine, and you understand the purpose of the exercise. You did it twice on the same page, and you should refrain from grinding the exercise as it'll only hold you back from the further lessons. In your warm-ups try to use the entire page for the exercise so it can further push your spatial reasoning, and take your time with the (optional) hatching.

Organic perspective pages show you have a good understanding of what the exercise is supposed to accomplish. There are diverging lines, but both the rotated boxes exercise and this exercise are both pretty difficult early on and the 250 boxes challenge will help you further develop the spatial reasoning skills. You can also probably come back to these exercises and crush it after the challenge

Overall I think you did pretty well, and you understand the purpose of the exercises. These will go into your 10 - 15 minute warm-ups

I wish you lots of patience on the 250 boxes challenge.
