Congrats on completing 250 boxes! Good job on it! I noticed you drew a couple extra boxes there. That's okay though. Better than falling short a couple. I've looked through your boxes and there's a few things to be said but nothing too major.

First off, boxes are a bit small. You want them to be less like boxes 154-167 and more like boxes 191-195 or bigger. Fill the whole page. Lines extend correctly but should be longer, especially on shallow boxes. Extend them fully, even if they take the entire length of the page and overlap with the other boxes. Example. Lines are confident but the silhouettes could have been superimposed since it makes the boxes more solid, plus you get some extra practice out of it. Boxes are varied in general. Good job on that! The only thing to point out in that regard is your initial Y angles sometimes fall below 90 degrees (boxes 155, 157, 185, 200, 207, 240, etc) which should never happen unless the boxes sit on the horizon line or on some special cases with extreme foreshortening. You could check this diagram for that. Your back lines tend to diverge/be parallel from the initial Y unless they are forced to converge too much via error accumulation from the outer lines. Take a look at this diagram in case you haven't already. It shows how to think about the relationships between lines instead of in pairs.

That's about it. Boxes improved a good deal over time. Good job overall. Again, congrats on completing the challenge. Good luck with lesson 2!
