I like the way you can just about make out the camera in her hand. If you have photoshop you can drag a selection around the girl and the bag at her feetand run unsharp mask on just that selection which might make her stand out a teeny bit more.
There’s a ‘sharpen’ brush on the tools palette which can be quite useful too (its there with the blur/smudge tool). Lets you brush in sharpness gradually, but use it at a 5% setting and build up the sharpness slowly rather than go at it full whack.
8) Despite the fact that it lacks a degree of sharpness, I really like this image. The composition is spot on, and the softness of the image overall draws you to its sharpest point, the subject. A good candid shot in my opinion. 8)
