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

Starting with your superimposed lines, these are looking good. They’re smooth, and properly lined up at the start, but not always of a consistent trajectory. The ghosted lines/planes look quite confident, too, and I’m pleased to see that the only issue I noticed in them, one of overshooting your end point, has been fixed by the end of the submission- well done. If I had one recommendation, it would be to plot some start/end points for the non-diagonal center lines of the planes, too.

The table of ellipses exercise looks good. Your ellipses are smooth, and rounded, though sometimes drawn through a little too much. Remember that the recommended amount is 2-3 times, ideally 2. Be careful, also, that you’re not committing to a mark too early. I notice that some of your ellipses start off a little stiff, then stabilize in the 2nd and 3rd rotations, indicating that you might be lowering your pen a little too early. Finally, when it’s time to finish the mark, lift your pen off the page, rather than flicking it off. It’ll get rid of those tails at the ends of your ellipses. The ellipses in planes exercise is nicely done. Your ellipses maintain their roundness, despite the added difficulty of having to touch all 4 sides of the plane. They do a good job of that, too. Finally, good job on the funnels exercise. Your ellipses are mostly evenly spaced, and cut into two equal symmetrical halves by the minor axis. Spending a little longer ghosting each one will improve them even further, but they’re fairly okay as they are, too.

The plotted perspective exercise looks good, though you’ve missed a backline (bottom-left box.) The rough perspective exercise is mostly good, but there’s a few things to point out. First, remember that what you’re doing here is no different from what you were doing in the ghosted lines/planes exercises: you’re drawing a line from point A to point B. If it can be confident there, it can be confident here, too. Be careful, also, not to correct an incorrect line, regardless of how it turns out. That’s called automatic reinforcing, and it’s very discouraged, as all it does is draw the viewer’s attention to your blunders, rather than the intended effect of hiding/fixing them. It’s much wiser to leave your mistakes be, usually. As for your convergences, these look good, though I’d perhaps spend a little longer planning them, next time. Remember that there’s no need to stick to your original guesses. Once you’ve got a point on the page, ghost it again, to confirm that it’s correct. If it’s not, feel free to replace it. Great work on the rotated boxes exercise! It’s missing 4 boxes (the corner-most ones), but what’s here is good. The linework is solid, the boxes big, snug, and comfortably rotating- well done! Finally, the organic perspective exercise is really well done, too. You’ve got some interesting compositions here, and as a result of the shallow, consistent foreshortening, and gradual increase in size of your boxes, they communicate the illusion of flow quite well.

Solid work on this lesson, I’m happy to mark it as complete. Best of luck in the box challenge!
