Congratulations on completing the 250 Box Challenge!

You did a good job on the challenge. Your boxes are fairly well constructed throughout the challenge. I can see that your mark making quality improved as you progressed. Your lines become straighter and more confident looking overall and you did a good job of getting your added line weight to blend more seamlessly with your previous 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 I noticed about your added line weight is that at times it is inconsistent or too heavy. If you look here you can see that the added line weight is placed around the silhouette of the box and not on any of the internal lines. You can also see that this added line weight, when done correctly, is very subtle. In the future you can try adding your line weight in a single pass too help with this.

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!
