It unnerves me a little how the different pieces overlap so that some of the squares are cut off in funny ways. I think I'd like this more if you had the same general shape and the same variation in the sizes of the squares, but had them more fitted together (like bathroom tiles?) instead of overlapping.
But who knows.
Anyway, I like the colors you chose for this. It looks a little dull on screen, but I bet it would look fantastic in print. I really like blues and oranges together like this.
