Dragon Titan) Wings need a better UV Map? They seem to be too bland, like you stretched them over a miniature part of the skin.
Whitemane Druid) Whoa, too pwnage to need editing.
Assassin) Claws seem too long. I personally think they look wicked cool though. Also, thongs? What kind of Assassin wears thongs? Unless it's a Sex Icon/Assassin hybrid, full-cover (though perhaps tight) pants are lacking and replaced by a cheezy thong.
Crusader) Needs a pwnage helmet to match the rest of his body. Even a reskin would work. He just needs player-color or some sort decal on his helmet and/or a bit of "spacing out" to make it like a captain's helmet. Aka, lower the faceplate and slice it down the middle and separate the plates a bit. |
