I like the simplicity of the piece to be honest, but I think it could use a bit of depth work I would blur the tree trunk on the right a little bit and have more of a blur on the plant behind the tree trunk to add depth. The lighting is alright on the left but it's off on the right side, there should be a light source coming from that direction to match the light on the render it's self that or darken the left side of the render a bit, I like the lighting on the finger tips but I would have added some liquid lighting to the tips so it had like a liquid trail on the light spots would be a nice touch I would also dodge and burn some area's on the BG to make it more accurate with lighting.
