damn that's some really nice texture work, the fact that it's all hand painted diffuse makes it all the more awesome! It'll be cool to see what the bottom half since it doesn't seem that he's just a biped.
*now seeing it at full height* damn that's a tall mofo, not gonna mess with him ;) . Once again, great work, your painting skills are awesome if they can carry all the weight of the diffuse and the spec and everything else in one map.
