Congratulations on completing the 250 Box Challenge!

You did a good job overall! Your boxes are were well constructed with a lot of confident looking lines and I can tell you put in a lot of time and care into completing the challenge to the best of your ability. By the end of the challenge you do a much better job of getting your sets of parallel lines to converge more consistently towards their shared vanishing point.

When I compare your first few pages of boxes to your final pages (and the extra 50! you did) I can see you tried adding extra line weight to some of your boxes. You did a pretty good job, though I see a few areas where you might have hesitated a little. When you go to add weight to a line it is important that you treat the added weight the same way you would a brand new line. That means taking your time to plan and ghost through your mark so that when you go to execute it the mark blends seamlessly with your previous mark. This will allow you to build and create more subtle and clean looking weight to your lines.

Finally while your convergences do improve overall I think this diagram will help you further develop that skill as you continue through Drawabox. So, when you are looking at your sets of lines you want to be focusing only on the lines that share a vanishing point. This does not include lines that share a corner or a plane, only lines that converge towards the same vanishing point. Now when you think of those lines, including those that have not been drawn, you can think about the angles from which they leave the vanishing point. Usually the middle lines have a small angle between them, and this angle will become negligible by the time they reach the box. This can serve as a useful hint.

Great job overall and good luck with lesson 2!
