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

Starting with your superimposed lines, these are looking great! They’re smooth, properly lined up at the start, and of a consistent trajectory. The ghosted lines/planes look quite confident, too, though I do have a few recommendations. The first, is to plot some start/end points for the non-diagonal center lines of your planes. The second, is to maintain a constant speed throughout, rather than slow down at the end, in an effort to not overshoot the end point.

Moving on to your ellipses, the table of ellipses exercise looks solid. I definitely think you’d benefit from ghosting a little longer, but that’s something you’ll develop a feel for over time. If you can, by the way, see if you can lift your pen off the page at the end of your rotations, rather than flicking it off- it’ll get rid of those tails at the ends of your ellipses. The ellipses in planes exercise looks solid- your ellipses are confident, and still fairly rounded, despite the added challenge of having to touch all 4 sides of the plane. As for the funnels exercise… 3 pages of it is a little overkill, though I understand the reasoning. For the most part, they look good. There’s the occasional misalignment, and the occasional construction issue (fix the former by spend a little longer on the ghosting stage, not forgetting to rotate the page as necessary, and the latter by spending more time planning your construction), but that’s alright.

Finishing up with your boxes, the plotted perspective exercise looks clean. The rough perspective exercise is where you start running into some issues, partly because of all of the automatic reinforcing, and partly because of the convergences. In regards to the former, remember that each line is drawn once, and only once, regardless of how it turns out. As for the latter, try not to get too caught up in what you think a box should look like, and just trust the instructions. Since we’re dealing with 1 point perspective, 2 sets of lines need to be fully parallel to each other, and 1 set needs to converge. Try to pay more attention to your page, too. This is an acceptable mistake for page 1, but at the end of it, it’s pointed out to you, through the correction lines, so there’s no reason why it should be there on page 2, too. The rotated boxes exercise is a bit of a mess, too, what with the fact that some of the boxes haven’t been drawn through, or the spacing issues in regards to their far planes, but, here, this is perfectly acceptable. In fact, mostly, we’re just checking to see whether you’ve seen the exercise through to the end, to the best of your ability. I do notice that 2 of the corner boxes are faaar more sloppy than they should be, but you also took the time to apply line-weight/hatching, so I’ll assume this was an oversight that you tried to fix last second, and let it slide. The next time you attempt this exercise, take it a little slower, if you can, reading the instructions multiple times, if you have to. Finally, the organic perspective exercise looks good. You’ve got a BUNCH of boxes here, of consistent, shallow foreshortening, and a believable increase in size. As a result, they flow quite well. The boxes themselves are occasionally a little off, but that’ll be taken care of in the box challenge.
