i'm not a great cold-one fan, but i like what i see here
maybe some of my ideas will help....
first, i think ZILLA is right, don't cover the great muscles with a armor. i like the idea of a chain made out of bones with a skull in the middle, but not to big.
ok, the rest, starting at the bottom:
the legs are great! the armor-plates an little skull/bones fits very well! maybe the loinclothes fits better, if you scult it like a plate out of stone or bone? or you put some aztec symbols on it?
at the hip maybe a little mace? out of bone? cause we have seen belts with trophys sooo much...
the thing with the chest is above...
the arms could be more decorated with some barcelets, the same with the tail.
the head is amazing! i wouold like some scars, that makes him looking more brutal and more like a veteran.
the back needs something, but what? for my taste there are to many spikes, it looks to unvaried. on possibility could be a small shield that covers 1/3 of the back. or here would be a nice place for the demon skull you were talking about
i'm realy loking foreward fore more photos
PS: i like to see all sculpts, but this is the AoW Forum, i don't know what Felix thinks about other sculpts...
