[CleverNameHere]: Here's Cloud's KH model:
It's, uhh... pretty much completely different. Different shading, different face, different muscles... In fact, Mike.S.N_310-X's model is far more accurate to the movie than KH's (and a hell of a lot more intricate), and quite frankly, the style doesn't look like Square-Enix's work at all.
There's always the slim possibility—with this or with any model—that it was ripped from some other source and then edited, but without anything to go on we'd have to check it against potentially thousands of games and millions of models, so we'll assume it's not ripped unless someone can come forward with what it was ripped from.
