Took Off

First of all: I won't talk about the model look, she's marvellous but that doesn't make a good photo by itself.
The good things:
The pose: it is curvy, enphasizes the action and the face hidden by the hair moves emotionally the viewer, which is good;
Light: I like natural light and a sunny day is a good way to enhance shapes with the strong shadows, the white or at least light toned walls and floor help you a lot reflecting sun light on the model, if done on purpose that's a very clever idea;
The idea of use a saturated red in a BW picture is nice, but I'd have kept it on a single thing, at best on the panties and the shoes... the coloured nipples look fake and anyway distract from the rest of the things you decided to stress in red.
The not so good things:
The textures: the textures playing around in the picture are nice, but they are messy in the composition, it is hard to find a rule in what I see;
The framing: why and I mean why! did you cut the head <img src="e.deviantart.net/emoticons/f/f…" width="15" height="15" alt="" data-embed-type="emoticon" data-embed-id="380" title=" (Sad)"/> you should try to keep the entire model in the pic if you want to shot a photo like this, or if you decide to cut it do it where the eye doesn't get hurt. Moreover the lines in the picture are slightly oblique which is bad because they are not perpendicular nor totally oblique;
Composition: same thing I said about textures, the image seems messy, try to find a different spot where you can shoot or a different angle.

That said, those critiques are my own suggestion and you shouldn't take them as a rule or an attack to your work, they are meant to be constructive and help you to shoot great pictures with your beautiful model.
