Hello and congrats on completing the challenge. This can be a tough one but you worked through it. Looking over your work I'm glad to see that you followed directiosn and extended your lines back to check your work on these. This really shows you how off you can be in some of your estimations. You always want to be thinking about the vanishing points when drawing the lines for your boxes in order to determine your convergences.

Now I'm definitely seeing an improvment in your overall consistency as you worked through this challenge. I also liked you were consistently changing things up and try narrow and more extreme foreshortening and boxes with more extreme dimensions. This is a great way to practice instead of just doing the same exact box and angle over and over.

One recommendation I have for you is to take your time when you are hatching your boxes. Right now you are doing a good job on some of them and the other just simply feel rushed which gives your work a sloppy appearance. If you are going to bother with hatching you might as well do it right to build a good sense of muscle memory for it instead of simply rushing and learning nothing. This is even more apparent on the last couple pages where it seems like you just wanted the challenge to be over with which is understandable.

That said this was a good submission overall with some nice improvement. There is still plenty of room for more improvement here though so keep up with boxes during your warmup exercises. I'm going to mark this as complete and good luck with lesson 2.
