Lines

Pretty good in general, you're focusing on confidence over accuracy in most of them. Only issue I can see is that on your superimposed lines, your lines tend to wobble a bit. Your main objective should be to make those lines as straight and confident as you can, even if the accuracy gets awful. If you keep practicing like that, the accuracy will improve with time.

Ellipses

Pretty good in general too, good confident ellipses. Though you have some that have a little bit of wobble. Here as well confidence > accuracy.

Boxes

Here I can see you're repeating some lines. All over the course, when you get a line wrong, don't repeat it. Keep going as if that line was correct. You're doing mostly a good job keeping vertical and horizontal lines in the rough perspective exercise, so go good job on that! I can see that your lines here get a bit of wobble. Remember that every line is a ghosted lines exercise, and you should approach it just like you did on it.

Rotated boxes is good, corners kept close and most of the boxes are rotating.

And lastly organic perspective, once again don't repeat lines. Remember you can add lineweight to clarify overlaps with a superimposed line as well. Perspective has mistakes, but don't worry about it as you'll work on it in the box challenge.
