Nice job finishing the challenge!

I'm making this as complete, however:

On a couple of the last pages you've played around with your boxes a bit, to the point of ignoring the point of the challenge (several boxes aren't drawn in their entirety and you haven't extended many of them.)

With this program, it's not about being entertaining, it's about the skills you learn.

Make sure to take lots of breaks and draw fun things too on the side, don't try to combine draw a box with more fun things it'll just lesson the value of both (if drawing boxes in different arrangements is fun to you, by all means do it, but it's not suitable for this course or challenge, especially when you don't follow the rules)

I really think you will learn a lot from this course, you already have! But you have to pay attention to what the exercises call for if you want the most out of them.
