Yo, TA qzhans here!

Before we begin, I just want to congratulate you on giving those 250 boxes a good ol’ pen and ink smackdown. It is a MASSIVE undertaking and you’ve joined the prestiged club of its completers.

You’ve painstakingly drawn through all your boxes and extended every single last line out to check your errors, and your boxes have been better for it. Indeed, you’ve made a marked improvement throughout the set.

Your general understanding of convergence is nice here. There's an obvious internalization of when things are converging or diverging, and your boxes feel very solid as a result. Some of your middle back lines are still stubbornly not jumping in line with the rest of them, but that’s okay. It's something that gets ironed out over time, but I’ll offer some advice. When you go to draw a line, think only about the lines that are supposed to be parallel to it (share a vanishing point). Lines closer to an existing line will converge slower, while the opposite is true for lines further away.

Your linework is good too, being both confident and accurate. I also like how you've used line weight to reinforce the silhouettes of your boxes and help them pop out. However, I do notice that there are some places where the line you've used to reinforce can get a little wobbly. Remember to always execute strokes with confidence, placing that above accuracy. In addition, there are places where you seemed to have re-drawn your lines quite a lot, going over the line again when the first one didn't go your way. Try to resist the urge to do this; it only draws eyes to the mistake that you made.

In terms of variety, you've drawn most of your boxes in the same orientation and size. It's always about a sixth of the page, with no particularly distorted faces. This is a pretty common pitfall, so just remember to jazz it up with boxes that are almost facing us head-on or particularly big ones when you pull these out for warm-ups.

Overall, this is a solid submission. I have no qualms about passing you onto Lesson 2!
