At first I couldn't find any mistake but I wanted to help you improve so I kept on looking. Watch out for the anatomy, there's something odd going on the left side of her chest (left from our perspective) and her left forearm (left from her perspective) is a biiiiit too long. I think.
But other than that, it's almost perfect. I especially like your new style, very painting-y and you are becoming very good at picking colour schemes. Oh, and I see you are getting better at perspective, keep it up!
