Congratulations on completing the 250 Box Challenge! You did a great job overall and I can see a lot of good improvement in your work.

When I compare your early boxes to your last few pages I can see that you do a better job of constructing your boxes with clean and confident looking lines. You are more careful with your hatching which makes your boxes look much better overall. I can see that you also did a pretty good job of adding additional line weight to your boxes. You also do a better job of getting your sets of parallel lines to converge more consistently with their shared vanishing points.

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!
