Howdy, 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, with some of the boxes on that final page reaching laser cut precision.

In general, I like your linework here. In the beginning, you had quite a few boxes where you had really sketchy lines, but that seems to have ironed out towards the end. I do wish you would've experimented with line weight a bit more, however.

Also, although you've done a pretty good job with convergences, some of your middle back lines are still stubbornly not jumping in line with the rest of them. That’s okay, and is 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.

Additionally, you have drawn a lot of your boxes quite small. If you're going to use this page size, there should be a few pages where you fill the entire thing with the box, etc. Right now, most of your boxes are about the same size.

Overall, your internal understanding of convergence seems to be coming along quite nicely, and I don't think the nitpicks that I have are worth holding you from the rest of your journey. Good luck on Lesson 2!
