no, eck is right about too much dither. or at least, you're dithering in places where you shouldn't.
a summary:
- i think you should drop the blue skintone.
- hair needs a darker shade
- eyes need a darker shade
I also think you might do better with a reference with different lighting. The problem with indoor/flash photography sort of stuff is that the light source is the camera, and you don't get shadows like you would if it was lit from elsewhere - so it doesn't define the planes of faces, or whatever the subject is, terribly well. Whereas in strong light you might get something like:
(which doesn't really look like you, but whatever. what i'm saying is that with different lighting you'd get better definition in the facial features.)
