I actually think it bears no resemblance to Uutton's lol
anyways the left side looks OK (a bit cluttered but meh) but on the right side, as others have said, every pokemon barring victreebell (and gold) has a crappy render.
The pokeballs look ok, but you failed to notice that the glare on each is in a different place; this makes them look a bit weird.
The bottom row is just... there. For no reason. I suggest you get rid of it.
Lastly, the font is an extremely odd color. It contrasts too much with the background. maybe red and black?
