Hello, im Natt. and here is my feedback for you.

First thing, i think you have already know it - that you have made this homework digitaly.

Because of drawing digitaly, everthing you draw seems to be almost perfect. That can be a big disadvantage for you though.

Because your boxes look very perfect plus you didn't organize them in order from low number to go up, it can make me (or maybe even you) harder to figure it out how much you improvement is.

About mistakes, i don't see many mistake from your homework though, acording to the box challenge feedback guide. Or maybe just because of my lack of critique experience. But DO see that you are worth it to pass this challenge.

I would like you to recomment you to practice more in a traditional way and practice more advanced exercise like to cut boxes apart, twist them, try to learn how to manipulate them in forms that you like them to be. You will start to learn stuffs like that from now on, start with the next lesson.

I appriciate your hard working to do this exercise and to give feed back to others too. I really am.

keep working, thank you
