I really want to love this piece but I just can't... the lighting seems to be all over the place from the drop shadows and hair highlights, proportions seem wrong, like her chest is oddly shaped but mostly the fact her waist is front facing, her legs are twisted and her head comes back on itself. I understand you have purposely hidden the hands but the clothing doesn't make sense and the background is a bit too much going on and really takes away from the main focus.
I think it's cute, lovely bold colour pallet and clean design. Just need to remember that when you are working with only a few lines, the key is to get them right.
Looking forward to seeing your style develop
