i think it looks great, really demonic. the character doesnt look like he fits there though to my eyes. i think its the lighting on him, the room is very dark with just that inferno for light, it would change the character.
edit> in particular maybe hed look cool if he was a silhouette with flame coloured highlights and perhaps blue shadows, thatd be something id try but im no expert. its tough because you still need him to stand out if its a game.
