Congratulations on completing the 250 Box Challenge!

You did a good job on the challenge overall. I can see by comparing your early pages to your final sets that you made a lot of good progress with improving the quality of your mark making. Your lines steadily becomes straighter and more confident looking as you moved through the challenge. I can see you gave the same effort to the extra line weight that you added to your boxes. At first you had some wobbling and hesitation showing in your mark making. But by the end your extra line weight does a good job of blending more seamlessly with your original marks. You also do a better job of getting your sets of parallel lines to converge more consistently towards their shared vanishing points!

One thing that I notice about your boxes is that you appear to have drawn them quite small. While it is a good idea to practice drawing at different sizes whenever possible, it is generally recommended that if you can draw bigger, you should. Especially with boxes as drawing bigger helps engage your brain's spatial reasoning skills, whereas drawing smaller impedes them. So in the future try drawing your boxes larger so that you can get the most out of your practice.

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!
