Well, the two biggest things I'm seeing is that first, the color looks a bit off. The person there on the left looks a little "ghostly"...I think I'd play with the saturation a bit more, but watch the pinks in the hair so they don't blow out!
Secondly, to me the image looks just a little on the soft side. Most of the time this isn't something I worry about at all and for a regular print or something I think it would be fine, but if this is for a contest, I think the image could use just a little more "pop". I also think I might try and clean up that lower left hand corner a bit...there's a bag or something there and while it's blurred, there's a face there too that's a bit distracting to me.
Based on your explanation of the theme, I do think you have good subject matter here, I just think the image could use a little more polish before you submit it. Hopefully others will have some better suggestions as well.
Good Luck!
Jim
