Hi Odingrey! I'll look at your work to see if I have some critique to give you.

To start off, I'd like to ask you something. Have you been constantly using your shoulder to draw? On some exercises, I see very straight lines (ie: ghosted planes, rotating), but on others like rough and organic perspective, I see some wobbling and some curved lines. To prevent hesitation while drawing these lines, make sure you are placing your points exactly where you want them and then focus only on ghosting after that. In other words, think about the perspective as you're placing your points, and forget about it while you focus on drawing a straight, confident line.

Lines exercises:

Apart from a bit of wobbling, you did pretty well. Remember that a wobbly line is always a mistake, even if you connect the two points. A straight confident line is always a success, even if it misses the mark even a tiny bit.

Ellipses exercises:

Ellipses are fine. Some are a bit wobbly but you're not expected to get it nicely right away. However, some of your ellipses are pinched or uneven, but judging by overall performance, you must already know that. Remember that you should prioritize smoothness and confidence over accuracy while drawing your ellipses. Ghosting helps tremendously.

On funnels, the minor axis (middle line) should cut your ellipses in two symmetrical halves. However, it looks like you made this mistake because the sides of your funnels are not evenly placed from the center line. In that case, it's a planning mistake more than a markmaking mistake. But do mind that next time!

Boxes exercises:

-Rotating boxes: You did a very good job on the perspective! Most of the lines you drew through your boxes make sense. However, I see little rotation on the boxes near the far end, as they mostly seem to be converging to the same vanishing point. Here's an example to illustrate what I mean

-Rough Perspective: Apart from a couple curved lines, you made one mistake: some of your boxes aren't aligned with the horizon line. The width lines should be parallel to the horizon line and the height lines perpendicular to that.

-Organic perspective: Lots and lots of wobbling! I can't find any points, so I assume you skipped ghosting in this exercise.

Apart from that, you did a pretty good job. It's normal for the perspective to be a little off, because you'll work on that in the 250 boxes challenge.

Overall, you did a decent job but much of your lines in the last exercises lack confidence. Remember to not skip ghosting as it will hurt you more than anything else.
