I don't find either image flattering. Back off in the photoshop and concentrate more in the actual photography. The first image has a weird color to it, a hand cropped off, is shot from an odd angle, and the lighting is harsh. The second photo- well, why are you hooting a Stephanie Meyer twilight cover? The selective color isn't enhancing the image. The fingers are out of focus.
I would work more with exposure and lighting, and try to take a flattering image instead of trying to compensate with hat tricks in post processing.
