I'd say lay off on the intense desaturation. It looks cool for some people, but other photographers or educated people may or may not dislike it. There is a difference between neutral colors and just low saturation.
Other than that though, 1 is really cool, maybe have one of the cords plugged into an outlet, which would become part of the background in a looser composed one. The missing mouth is cool too, it says (lol pun) the message rather well. I'd say try taking some skin from your arm (where it's in focus) and then changing its colors and whatever. It seems to have more of a texture there. It looks like you just dragged the brush across. Are you using 0 hardness on the clone or healing brushes? It will help soften the edge, so you can't see where you dragged the brush. Also, try taking other shots of your face under the same lighting, and move your face so you can get good spots to take skin from.
The missing mouth thing is an awesome idea, just imporve the photoshoping. Also, what's that circle spot on your pants in the first?
