Congratulations on completing the 250 Box Challenge!

Before we begin I just want to mention that in the future, when you go to scan your homework submissions, it would be better to scan your homework using the "photo" setting instead of the "drawing" setting. The drawing setting tends to up the contrast on an image and can cause you to lose some of the subtlety in your line work.

You did a good job on the challenge. Your mark making improves a lot over the course of the challenge. I can see that when I compare your early pages to your final sets, your lines are straighter and more confident looking. I see that you also experimented with adding extra line weight to your boxes and by the end of the challenge you do a better job of getting your sets of lines to converge more consistently towards their shared vanishing points.

One thing I notice about your boxes is that your don't have much variety in your foreshortening. In the future I recommend you try drawing your boxes with more dramatic foreshortening, as shown here.

I would also recommend that you continue to experiment with adding line weight to your boxes. You did a fairly good job with the boxes that you tried this with, so just keep it up and you will continue to improve with time. Just remember, 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.

Congrats again and good luck with lesson 2!
