Heyo! Let’s see...

Starting off, your lines are really good! I notice a bit of an arc on your superimposed lines, so be mindful of that. I also quickly want to confirm that you’re superimposing them 8 times- no more. In regards to your ghosted lines/planes, I’d recommend making the start/end points a tiny bit smaller, and actually using them for the non-diagonal center lines of your planes.

Moving on to your ellipses, they’re quite confident, too. Be a little more attentive to their rotations, though. 2-3 is the recommendation, ideally 2. (You’ll settle for 1 and a half, sometimes.) In the ellipses in planes exercise, they’ll occasionally come out a little deformed. Remember that the priority is for them to be smooth, and rounded- not accurate. In the funnels exercise, be a tiny bit more careful about their alignment to the minor axis.

Finally, the box section is really nicely done. The first thing that jumped out at me is the line-weight- it’s really thick! If you’re using a different tool for it, don’t- the pen is enough. If you are using the pen, try to be a little more subtle- a single superimposed line is enough, most of the time. Also, in the organic perspective exercise, the line-weight should be applied locally- that is to say, to the relevant parts of the line, rather than to the entirety of it. Getting back to the correct order, the plotted and rough perspective exercises look good, but be careful not to redo lines. If a line is wrong, it’s wrong. The more difficult exercises of this section, the rotated boxes exercise and the organic perspective exercise are quite well-done, too. There’s a few diverging boxes in the organic perspective exercise, but we’ve got just the thing to fix that~
