I'll admit that this critique is going to be a little off, especially as I'm not all that familiar with the Pokémon fandom. The photo manipulation is very good. It looks almost like the poke ball was actually painted that way, although that might not be how you wanted it to seem. Try switching the decoration on the bottom half with the decoration on the top half. Also, try using different art. Also, if you used, maybe an red background with a fade to black outline, it would make your design pop a little bit more. I hope that this helped.
