It seems a little odd that she is biting the hand, it looks.. Well.. Wrong it seems like the hand should cover her mouth instead, otherwise it doesn't seem to have a purpose by her face. Also the model appears to be completely unenthusiastic and lacking emotion, like she is bored.. Just my thoughts. Thanks for reading them, sorry if you don't like them but they are mine to think.
Thank you for such sincere critique! That's an interesting point of view. While the hand covering her mouth would make an interesting picture, it just doesn't match the meaning I intended for this one. However, I don't agree about the lack of emotion on the model. She's raising her eyebrow and to me she looks kind of defiant or ironic. Of course, appreciation of art is mainly subjective so you're not supposed to feel as I do when looking at a picture.
