Neat idea. I wish the horseman were more centered, though. Something about the eye-catching element being up at my shoulder doesn't sit will with me. The light splattering and the hill being a bird are nifty touches, though. Overall, I'd say a 4.
That is one of the best placed giant wings I've ever seen on a tee! I wish there were even more galloping horses and etc on the whole wing, but this is still more than enough awesome abstraction to warrant a print and a buy from me.
