Read some tutorials on blending, lightning, flow and depht..
The ship and the BG is ponting in the same direction, but the anime figure with a gun in his hand is pointing in the opposite direction, thus killing off any flow.
There is no sense of depht, the image seems flat and the ship and the anime figure seems litterally slapped on like a sticker.
The colors dont match
The direction of which the ship is illuminated is opposite of the direction the anime figure is illuminated. One must keep the light source central for all parts of the sig or it will seem messy....
