Skins of Orc Troll Batrider: CnP on faces, hand-drawn abrasions all over Troll, skeletal wings, recolored swinging weapon slightly
Edit: Completely changed wings; freehanded (looking off wyrm wings), added some skin in wings (otherwise you get bad 2-D effect), changed rest of trolls body to green to blend with his face, made ears looks undead (freehand)
