The shading is extraordinarily generic.

Try using the shading to show the shape and texture of the body and articles of clothing, to add personality to the skin.

As it is now, the shading looks like it could have been made automatically with something like this: Instant Shading. Or, in other words, it's not interesting or unique.

Besides all that, though, I do like the details you put on the skin, like the zipper and stuff on the front of the jacket.

Nice skin! you got a new subscriber and favorite!
