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. I can see quite a good improvement throughout the set, even though your first ones were quite good already. There are a few things we can discuss still, however.

In general, I like the lineweight you've applied, but in some places it can get a little wobbly. Remember to ghost these as well and execute them with confidence. Additionally, the extended error lines you used to check your boxes tended to be on the short side. Don't be afraid to extend them out really far, even through other boxes, to check how far off you were. Finally, a minor nitpick: I would've liked to see some extra big boxes on some pages, but you can always chalk that up for warmups.

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.

Overall, there are places where you've redrawn lines or haven't executed with confidence, but in general there's a lot of good patience and technique applied here in terms of linework, and your understanding of boxes seems to be growing fine. I'm excited to see you bring that into the rest of DrawaBox!
