I really really like the effects, and the simplicity. However, i don't like the tealish background colour :(
looks too grainy to me - smooth out part of aqua's face maybe? also, the... whatever in the bottom right corner is kind of distracting. liking the colours though.
idk, it looks a bit oversharpened/grainy (bottom left part of the bg specifically). I like the colors you're using but you should give it a bit more depth(?) or flow
