This is an AWESOME design, though it could have used a little more contrast. There's a lot of cool shapes in your design that made it just a little harder to read the orange text, and that could easily be solved by changing up the style of the font a bit or making it darker (or a darker color).

This is one of the best designs I've seen for this contest. You should have considered keeping the art tools in there somewhere (though I can understand if you just couldn't find a good place in the composition for them).
