Hello, Azimuthzero. Congrats on finishing a hard challenge!
Having looked at your boxes, I think you pretty much nailed the challenge. Your convergences are mostly correct (converge away from the viewer. Your inner corners are also mostly within perspective. You've also drawn boxes in a good variety of orientations. Comparing your first and last boxes, it's clear that you have a good understanding how boxes sit in 3D space.
The only thing might need some work on is your linework - some of your hatching is a bit wobbly and frayed. Remember to ghost, start on the dot, and aim for confidence rather than accuracy. Overall, great attempt though!
Next Steps:
Move on to Lesson 2!
