If your going for the commercial/sponsorshiplook you should have the logo clearly visible. Also the colors are very flat in this photo. I realize there is a window beside you but it does not create any type of interesting light. Try to set up lights at different angles or wait for the light coming through the window to become more intense.
i would crop the doorway out because it is distracting. The light from the windows makes it look like the left side of the player's face is painted white.
I might put him in more a paintball environment. If you want him to be inside, I might shoot the wall up with a little paint and remove the plug from his right shoulder.
