The problem with the model is this.

The armor looks like it has absolutely no thickness. Look at the way it comes off the hips and thighs, etc. The armor fits like a pair of jeans. The armor on the arms has no thickness by comparison to the original. There's something about the chest, too. I think it might be the shallow taper of the sides of the chest, and those skinny hips.

He looks like a frail sissy.
