Can't quite put my finger on it, but there is something murky about the lighting. Not going to comment on the skin, despise the look of wet maps. Otherwise ok, I guess.

Not a sexy image to my taste... Put her in a japanese schoolgirl with some cats eye glasses, socks ( one of which is sliding down), sensible shoes (one maybe untied), a blunt bob hairstyle, a lollipop (or ice cream cone, or gnawing on a pencil) and a coy or coquettish expression in a conventional environment like a library with a good pose... then you might get my attention.
