All in all, these are solid pixels. Go crazy on colors if you want, just don't waste them. There are a lot of redundant midtones in the face area :p
That being said, rushed color edit incoming!!!
I overdid it, just to get the point across on what Xion Night meant about a hue shift (people have distinct personal preferences as to how they shift their hues and skin tones are really easy to screw up when shifting). I didn't add too much value contrast because of the way you distributed the colors, and you already had some pretty good use of saturation. I moved a pixel or two to compensate for the color balance but nothing monumental.
