I love the darkness, i think it fits with the orc's personality and character, if that was intended. The right leg ( non black one ) seems a bit mangled. Draw a bandage and it'd be a good add to the character i think. Some colour would look ace on this, very light though... as in, not much applied, because there is not alot of room it would overpower the image i think. Ace work, love it =D

Did you get a scanner in the end then =) Or a super digi cam
