I'm not a photography expert, but I am studying visual arts, so I'll do my best to help. (: Ah I just, I think it's gorgeous. The model's beautiful, the 3-quarter view fits really well. The wisps of hair add flow from the top of her head down. The teeth slightly barred is a great effective too. I just feel like her eyes are a little strange, like they should be either relaxed, or in distress, and right now they're somewhere in-between, which makes it harder to see the emotion being shown in the portrait. The black and white feels really natural. Well done!
Thanks for your critique. I think eyes is a really big thing for me. There is so much emotion in someones eye, you can read everything in it, about a person. But when I transfer myself into the model and not the photographer, I'm in the most beautiful world when I close my eyes. Cause there you can make everything happen.
But thanks again, I can really use your critique in my upcoming pics.
