First of all, let me start off by saying I'm impressed with your body of work. If I would not have been I would not have put you on my "watch" list. Also, I am no photographer but, I am an artist. That being said, I like the composition, the "S" curve of the way she's posed would make her an interesting subject to draw. Realistically though, what would keep me from using her as a reference for say, a charcoal rendering, would be the fact that it's too close a crop, and her pale skin against an almost equally pale background makes her appear to be a little washed out. Other than that, beautiful model and pose.
It is nigh on impossible to be truly original in this genre so it is incumbent upon the artist to exercise good technique; a responsibility heightened when, as in this case, the model is a beautiful women. Here this is achieved with élan. Composition is superb, with the object being placed to the left of centre our eye is drawn to it. Her pose too is excellent with a voluptuous, almost erotic curving 'S' shape; the head position fully consistent with it. I particularly like the cropping,especially where it runs along the middle of her top arm; this frames the shot most effectively. the colour too works most effectively with her underwear matching her outrageous hair colouring. My only reservation is the background, whereas the dark out of focus brickwork accentuates the pale, almost glow, of the model and brings out the rain there is too much clutter. At first I was not sure about the central white column but on reflection I think the straight line in juxtaposition with the curves on the model actually works; however, the light strip to the left side is distracting. Of even more of a distraction is the blue cylindrical object which draws our attention away from the girl - a definite no-no. Overall an excellent piece of work. Congratulations
