Wow, am loving your work. Great model and great pics. I don't know ay technical aspects of the art of photography so I'm unable to comment in this respect, but your pictures are emotive and evocative. And it takes art and talent to accomplish this. Your model is clearly comfortable enough with you to express herself in this way and the ability to draw that out of a model is something in and of itself. The second and last pics I find especially powerful. Nice work!
