Hi there Torben, I'll be handling your 250 box challenge critique.
First of all good news I can tell you have improved over the course of the challenge.
Your convergences have become more consistent and you end up with diverging lines less often. Your line work has also improved and things are looking tidier and more confident.
I do have a couple concerns though, while completing 250 boxes you didn't experiment much with varying shapes and foreshortening. You had more variety in the beginning and as the challenge went on it decreased, remember that building a strong understanding requires experimenting and creating multiple examples only benefits yourself.
So while you've shown improvement I can't confidently judge whether you understand working in 3D space, or just understand how to rotate the few boxes you've created.
With that being said I can't confidently move you on to lesson 2 just yet. I'd like you to draw 20 more boxes, experiment with shapes and foreshortening, have some with the vanishing point closer and see how the box reacts, try drawing thinner or wider boxes that aren't as cube like and see if you can keep your convergences consistent whether the vanishing point is near, or further away where lines get closer to parallel.
Remember we don't expect perfection, and you have shown improvement in ability already. I know being told to draw more boxes can be discouraging to people as the challenge is already hard on one's willpower, but showing not only the person critiquing your work but yourself that you understand the concepts being taught here is important.
After you draw your 20 additional boxes, add them to your imgur album, or create a new one and reply to this post with a link and I'll take a look. From there we can either move you on or address any weaknesses you may still have.
Next Steps:
Draw and submit 20 more boxes with more variety in terms of foreshortening and shape.
