Think outside the box (unfinished)

This is something I've been working for awhile. First I was not sure if I'll be brave enough to start colouring because I was afraid that I would mess it up, but then I pulled myself together and did it. I like how it turned out.

Actually this is unfinished, on the paper, I'm still working on it, but I think it would stand on its own like this too, so I decided to upload this version too.

Let me know what you think about it!
