I really like this, and didn't want to write a whole Critique. If I had to add anything, I would say that the shadows look off. The shadow on the inside of the head should be on the outside if light is coming from the left. It does draw attention to the missing part of her left arm (inside her right hand) which if done on purpose, works well. I also wish the shadow on the right forearm was lighter. After all that, it is still wonderful.
thank you for your comment. in the shadow of his head, which was intended is that it gives the impression of being flat, I do not know how to explain so it's not really a shadow, rather an effect like a paper off. thanks again really appreciate !
