Very solid triptych, with a nice combination between various types of photography and poses. Also, the choice for the brick wall as backdrop works well, it separates model and surroundings very nicely, but also adds to the image, and is in that way as much a part of the triptych as the girl herself.
One could argue the sequence of the photos, placing the close up in the middle to draw more attention to the model, but that's rather subjective.
I would consider equalising the tones and saturation, though. The middle one is a bit brighter and more saturated than the two photos flanking it...
