Thanks for the comments, and the edits are appreciated much.
Will try to fix the lips and AA when going back to it (though it will have to wait a couple of days, as I'm still sick of it :X), But I guess the wonkiness will stay. I'd prefer to move on rather than being stuck with this.
I'm rather happy about the colors though (btw thanks to helm for pointing out that yellow and how it should blend more, I'll take that advice with me for next pieces)
As for the AA, it is getting more of an automatic thing for me (knowing where colors should go and all, except when I'm tired), but practically, you just have to keep trying to use the colors you have, until it looks smooth and not blurry, much like a puzzle I'd say.
