I don't like this as much as your Evis. One problem with this color scheme is that the teeth end up looking too similar to the rest of the skin color. The paint on the skin doesn't seem very smooth, and that's probably what is bringing your score down the most. It could be the roughness of the original cast, or it's possible that you're layers of paint are a bit thick. If you're not thinning your paint down, I recommend that you start. (It's fairly easy to transfer it to a pallette and add a touch of water, and it also makes mixing colors a lot easier.) Remember; it's always better to have two thin coats than one thick coat.
