Superimposed lines: Looks very well done with not much fraying, however some of the longer lines are a bit wobbly; remember to always draw lines from your shoulder even if it is inaccurate. also i think with some of the longer lines you didn't use a ruler to make a base line first; if you repeat this exercise in your warmups remember to put in a line first using a ruler and then superimpose it by hand.

Ghosted lines,planes: Looks great, nearly all the lines are straight and hit their targets.

Table of ellipses: You definitely put in a lot of work in these! Most of the ellipses are quite compact and fit their spaces, however try not to draw over your ellipses more than twice.

Ellipses in planes: Some of the ellipses are drawn over 3+ times, but otherwise the ellipses fit really well in the frames.

Funnels: The minor axes of the ellipses match up in almost every case, and the ellipses fit in the funnel quite well.

Plotted perspective: Looks quite good, can't see any issues.

Rough perspective: Looks good, the 2nd page shows a lot of improvement, well done.

Rotated boxes: The boxes all look good, but I think you misunderstood the exercise as your boxes are barely rotated. Try going over the exercise instructions again and note how the vanishing points shift across the horizon line. You could also try exaggerating the rotations (boxes next to each other should not look similar)

Organic perspective: The variation in sizes of the near and far boxes is good, however some of the nearer boxes seem to have really parallel edges (usually the closer boxes should have more distortion than the far boxes). I think this will get better with the 250 boxes challenge.
