Howdy, TA qzhans here!

Before we begin, Congratulations! 250 boxes under your belt, neat and tidy. I'm pleased to see that you drew through all your boxes and applied the error checking method throughout the set. Even with the technique switch there's still a gradual improvement from start to finish.

You've done a pretty good job with convergences, but 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. This is helpful for boxes with very little distortion as it's impossible sometimes to even visualize the vanishing point.

I also like how you've used line weight to reinforce the silhouettes of your boxes and help them pop out. However, in some places the reinforcing line does get a little bit wobbly. Make sure to always have confidence in your pen work.

In general, there's some clear diligence here and I can see a good understanding taking root. I'm excited to see you take that into Lesson 2!

EDIT: Hey, seems like I accidentally requested revisions! When you reply to this comment, I'll mark it complete.
