Well, well, well, hellobaphomet, this is the first review I do about your art, so I hope my praise and criticism can help you improve!
First of all, I like the coloring you did for this one. I like how stylized, but slick the colors look. My favorite would be the use of black for the eyebrows, eyeliner, and iris, and the use of dark brown for the hair. I actually like how you managed to shade and combine the use light and dark brown. It's a nice detail.
I also like the background, especially the combination of pink and orange. I also see that you played again with the shades of dark pink, light pink, light orange and dark orange.
Overall, I like the facial structure of the girl of the illustration. Particularly the eyes, which I think are nicely done.
I think there are things you could improve: for example, the ears; I would suggest to play more with the size of them, in order for them tl be more asymetric to the head. Same goes for the lips; however, for the latter, the use of white and pink is good. I would only recommend to change the size.
I would also recommend to play a bit more with the noses; I know from experience they're some of the most difficult parts of the human body to design, but like the ear and lips, I'd try with different sizes and styles, see which goes out more with the overall illustration.
Initially, I disliked the girl's torso, but upon a closer inspection, I actually like it. It's not at detailed as the rest of the picture, but it is nicely done and I can see that you took your time on it. I like that the bones are palpable and the use of shadows for the neck and collar bone.
Overall, I like this piece; there is room for improvement, but is not a bad illustration. You're on the good track, keep it up and you'll end with a beautiful illustration, I can feel it!
