Hey, Opacus, this is looking pretty cool. Great colours and your improvement rate is really impressive. I've got just a couple of crits for you, and an edit to go with.
First has to do with the high colour count. You have way too many colours here, and it's making the pic look blurry. In the places I edited, I cut back the use of skin tones, and reduced the amount of AA. Sometimes a more simplistic approach can be better, or at least... cleaner. The hair, too, which I didn't edit, but which suffers from the same problem: High colour count and over AA'ing is making it look blurry.
Apart from that, I think your forms could use a bit of refinement. They aren't bad overall, but some things (the neck and hair particularly) look just a bit... I dunno, wonky? Again, though, this might be from the over AA'ing and blur, distorting forms and hurting readability and what not.
I like it. You have a great eye for colour. Congrats.
