I tried something like this years ago & I like the idea behind it. I think if the lady changed outfits for each pose it would be more convincing. :D Well done
I really like it, lovely tones in the shot and the vignetting really suits. I also like the idea. Love the eye contact between the images of the girl on the left and right. Some part of me feels it would be better without the image of the girl on the steps though also the text distratcs a little though.
