A definite keeper, exudes with not only sex appeal but femininity, you know what I mean.
Her overall tone is wonderful, protective yet inviting... of course, should be handled with care. Lips, eyes, parting of legs (bit too wide for me), are just right to compliment the shot.
Now, let's get down to the cons, eh.
Her right breast looks quite distorted, her arms, hands are oddly positioned... they do not compliment her and with that way that strap or whatever it is called, is positioned, that it is already down... it is as if, everything is too easy-- nothing wrong with a little more appreciation, I think. You know what I mean.
Her right leg, that one where it is kind of disappearing into wherever... exactly, where on earth is that leg going? It just feels off.
Now, almost anybody can turn a photograph monochromatic but it takes taste to darken and lighten, areas where it is deemed necessary to where you seem to be lacking.
If you look closely, well, not that close but yeah... the photograph is kinda divided into two segments, you got one where it is like a dream-state and the other reality. Might want to look into that.
That's kinda funny , well, matured funny and definitely appropriate for your chosen genre.
