I agree with Slynky, the eye needs to blend with the head better. Other than that, I see the figure in a basement type area (decaying wall structure...) with a hallway or the appearance of one coming from the right side of the image with the perspective receding towards the back (this will bring the focus to the character...). Offset this hallway so the character is not directly in the path of it. Place the character in front of the connecting wall that runs "east-to-west". You could even have the character appear as if it had traveled through the wall (giving it a mystical aspect...)

It's pretty cool now, with the right background and textures it'll be awesome.

my 2cents.
