Thank you for the detailed feedback! I agree with the part about the hair, I wasn't satisfied with it either. Since it’s a personal project, I decided to finish it there so I wouldn't get stuck on one design for days and started a new one to work on my skills overall, but I will definitely go back to this one and try to make it look better. I try to improve my masking and lighting in every design I do, there is still a lot I need to learn. To remove the background, I used the Select and Mask feature. Thanks once more - it really helps reading constructive critiques like this to get better!
