Hi hi! Let’s take this one exercise at a time~

Starting off, your superimposed lines are looking good. They’re confident, mostly lined up at the start (take an extra half a second, if you can), and of a consistent trajectory. If I had to give you one piece of advice, it would be to have your arcing lines be a bit larger. Small movements are notoriously difficult from the shoulder, and are best saved for later, once you’ve become a little more comfortable with it. Your ghosted lines/planes look quite confident. As I’m sure you’ve noticed, you’re lifting your pen off the page a little too quickly, so see if you can reel that back a little.

The table of ellipses exercise is a little strange. I’m not sure whether this is because your pen is dying (I do notice some really faint marks in the background), or an actual mistake, but your ellipses haven’t been drawn through the correct number of times, at least not consistently. If it’s an issue with your pen, please change it, as it makes judging your linework difficult. If not, then be sure to go around them the recommended 2-3 times. Outside of that, however, your ellipses look good- smooth, circular, and of a consistent degree/angle in a frame. The ellipses in planes exercise looks good, in that your ellipses maintain their smoothness/roundness, though these ones have the opposite problem- they’ve been drawn through too much, so be mindful of that. Finally, save for the occasional alignment issue (be sure to ghost each ellipse properly, rotating the page as necessary), the funnels exercise looks good.

Nice work on the plotted perspective exercise- it looks clean. The rough perspective exercise looks decent, though it still has a ways to go. Mainly, the issue seems to be that you’re rushing yourself, trying to get to the actual boxes as soon as possible, but the bulk of the time in this exercise is actually spent on the planning stage. Ghost and re-ghost each line, and, only when you’re certain that it’s correct, commit to it. The rotated boxes exercise is missing 6 boxes (the entire left column) and one corner-one, but what’s here looks decent. Your boxes are snug, and rotate comfortably, though their far planes are a little flat, unfortunately. They’ll get better as you progress through the box challenge, however, so don’t worry. Finally, save for some automatic reinforcing/scratchiness, the organic perspective exercise looks good. Your boxes properly follow the flow line, maintaining a consistent, shallow foreshortening, and increasing in size as they do- nicely done.
