Welcome to drawabox! Let’s see.

Your superimposed lines look fantastic. They’re smooth, properly lined up at the start, and of a consistent trajectory. The ghosted lines/planes look great, too; I’m glad to see that you’re lifting your pen off the page at the end of them. There’s some overshooting issues, that I notice don’t get better, even by the end of the submission, that you’ll want to take care of in the box challenge, and some hesitation when you commit, that does improve, so nice work there.

The table of ellipses exercise looks really good. Your ellipses are smooth, rounded, and properly drawn through. The end of these isn’t quite as smooth as their line counterpart, so I’ll recommend doing the same thing here – don’t flick your pen off the page, lift it off. Also, see if you can experiment with some more degrees, next time – your thinnest ellipse is 30-40 degrees. The ellipses in planes look good. Try to rotate around them a minimum of 2 times, however; not one and change. The funnels are well done, also. You may consider upping the difficulty next time, now that you’ve gotten your feet wet with these, by having the ellipses increase in degree as they move away from the center.

The plotted perspective exercise looks solid.

The convergences in the rough perspective exercise look good (though this is a little hard to tell, because you’ve extended them beyond the horizon). The linework has some issues. The first is the overshooting issue, that we’ve discussed. The second is one of confidence. It’s easy to forget, but there’s in fact no difference between these lines, and the ones in the ghosted lines/planes exercises (at least as far as the process of drawing them is concerned). So there’s no reason to get overwhelmed.

The rotated boxes exercise looks fantastic. It’s big, the boxes are snug, and they do a good job of rotating. You’ve also been mindful of your far planes, and your depth lines – both look good.

The organic perspective exercise looks good, too. Linework is, again, a little rough, what with the overshooting issue, and an automatic reinforcing issue (correcting an incorrect line), but that’s pretty much the only problem here. Certainly, the increase in size could’ve been a little bit more obvious, but the many overlaps, and the shallow foreshortening of your boxes, do a solid job of conveying the illusion we’re after, nonetheless.
