Congratulations on completing the 250 Box Challenge!

You did a pretty good job on the challenge. Your boxes are made of nice, straight and confident looking lines. You also do a better job of getting your sets of parallel lines to converge more consistently towards their shared vanishing points.

There are a few things I noticed about your boxes that I would like to go over. The first is the size of your boxes. You drew them quite small. Part of the reason for the 5-6 boxes per page limit is to allow you the room to draw your boxes large. In the future I would encourage you to try drawing your boxes larger. Drawing bigger helps engage your brain's spatial reasoning skills, whereas drawing smaller impedes them.

You also don't have much variety in the foreshortening of your boxes. In the future you should try experimenting with more dramatic foreshortening as most of your boxes have shallow foreshortening, as shown here.

I also recommend that you try experimenting with adding 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 previous mark. This will allow you to build and create more subtle and clean looking weight to your lines. You can read more about that here as well.

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!
