Hey, good job on finishing the first lesson. Full disclosure I am still on the 250 box exercise but I think I can help you.

Your superimposed lines look good. You're hitting the starting point consistently with some fraying at the ends which is normal. I can tell you're drawing with your whole arm because you have smooth, confident strokes with little wavering on your superimposed lines and your ghosted lines. You're undershooting and overshooting with some of your ghosted lines but that's to be expected and will be improved with more practice and muscle memory.

Your planes look good as well, the ellipses in planes exercise was supposed to be done on your ghosted planes pages, but I see you did another set anyway. If you want, you can fill in your planes with ellipses for more practice. I see lots of improvement in your planes lines though, good job.

Your ellipses table looks good. You're confident in making smooth ellipses and you're staying fairly close to the edges. Try changing the shape of some of your ellipses next time you practice them in your warm ups, you can practice thinner ellipses and even circles AKA fat ellipses. Likewise your funnels look good and consistent, and you're touching the edges nicely with uniformly divided ellipses.

Plotted perspective looks good, not much else to say here.

Your rough perspective exercise shows promise. You have a good gist of estimating your VPs and accuracy will inevitably be improved with the 250 box challenge. I'm noticing some more wavering lines as you're probably being more careful plotting your boxes. This isn't too big a deal, just make sure that you're still ghosting lines with your whole arm and not your wrist- even for the smaller lines.

Your rotated boxes are excellent imo. Obviously there are some inaccuracies with the VPs but that's to be expected with this difficult exercise. I can tell you're aiming for the correct VPs and you're staying close to the borders. Perfecting the rotating boxes and fully comprehending the perspectives will come in time with practice. Looks really good.

Your organic perspective exercise looks good, your lines are parallel for the most part. I can tell you've improved a lot on the accuracy of your ghosted lines. You have a lot of boxes with parallel VPs which is totally fine but you should try to incorporate closer VPs and practice some dramatic foreshadowing in your 250 boxes challenge.

All in all great job! Good luck in the 250 boxes challenge!
