In my opinion none of it blends. The background, and blur is really nice, but the aces currently don't work for me. If they followed the main colour of the background it could possible make it work, maybe try some linear dodge, or soft light settings on the aces. Theres just too many colours that don't compliment each other in the piece, and no real main colour, and just make it looks all over the place. You need some colour balances possibly, just to tone down the multi colours, and to compliment it by giving everything in the signature something similar which will help it to blend.
