Welcome to drawabox, and congrats on completing Lesson 1. Let’s take a look at it, shall we?

Starting off, your superimposed lines look good – smooth, properly lined up at the start, and of a consistent trajectory. The arcing lines less so, but that’s entirely due to their size (as you know, the smaller your marks, the harder it is to engage your shoulder for them); as such, I’ll recommend drawing a little bigger if you can. The ghosted lines/planes look quite confident, also. I wonder if you’re plotting start/end points for the non-diagonal center lines of your planes, though. If you’re not, be sure to, from now on.

Moving on to the ellipse section, the table of ellipses exercise looks good. There’s not a great degree of variety to your ellipses (referring to their degrees/angles), but what’s here is good. The ellipses in planes do a good job of maintaining that same focus on smoothness/roundness, despite their more complicated frames. The funnels, too, are well done, and I certainly appreciate the increase in degree of the ellipses as they move away from the center.

The plotted perspective exercise looks clean.

The rough perspective exercise starts off strong, and shows some nice improvement throughout the set. By the end, its linework is confident, and its convergences on-point, with little need for adjustment, as was the case with your first few attempts – keep up the good work!

The rotated boxes exercise looks solid. It’s big (huge positive!) and its boxes are snug, and properly rotating. The latter isn’t so much the case in the back – there, they tend to look a little flat – but that’s entirely normal, and I certainly prefer seeing that, than you ignoring the neighboring edges in an effort to rotate, so good call.

The organic perspective exercise is interesting. Linework is a bit of an issue here, but it seems like a large part of it is due to a misunderstanding. Namely, a box overlapping another should not hide its lines. In thinking that it should, you’ve had to stop your lines short, quite accurately, too, which has led to them wobbling. Beyond that, however, the boxes are well constructed, and flow well, as per their size, and foreshortening, so no stress.
