Congratulations on completing the 250 Box Challenge!

Looking at your work as a whole I can see you made a lot of progress with improving the quality of your mark making. You do a good job of drawing your boxes and their extensions correctly. You also do a better job of getting your sets of parallel lines to converge more consistently towards their shared vanishing points!

One thing I notice about your boxes is that you drew many of them quite small. Part of the reason we have the limit of 5-6 boxes per page is so that you can draw your boxes all at a good size. Drawing bigger helps engage your brain's spatial reasoning skills, whereas drawing smaller impedes them. Try to keep that in mind for your future warm ups.

I also see that you made some good progress with adding extra line weight to your boxes. 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 original mark. This will allow you to create more subtle and clean looking weight to your lines that reinforces the illusion of solidity in your boxes/forms. This is something that you will improve with consistent practice, so make sure that you include this step in your regular warm ups.

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.

Congrats again and good luck with lesson 2!
