/ic/ - Artwork/Critique

Looking to self critique and get constructive criticism thinking to myself what can I focus on more in general. The generic deadpan doll face is all and well in the sake of practice but I can't tell if anything else in the face is off. The hair gives me red flags in that I don't think it compliments the face (or is painted or rendered as well), I can tell my lack of knowledge for painting hair and so I could focus on hair tutorials but I can't tell if it's a matter of learning and practice or if there's something specific to learn that I'm lacking atm. I struggle with ears and if I had more confidence I feel the ears could be painted/rendered much better. Finally maybe a background would help bring unity and distract from the things I'm not so good at and give an overall sense of completed composition. Any other things to consider would be great help.
