To be honest, what happened? The only construction at all that i can see in this work of yours is that she is only slightly lighter in background highlight, than the rest of the environment. An issue that presents itself here is that she should be better focused on the edges. Also, your subject's environment should not be such a blank slate. The environment around your subject should lead into them, through flow. Though your right side somewhat does this, the left side has no way to compliment and balance for your subject. In addition, your background has no sharpness to it at any point. Though you should not entirely focus your background, you should realize that in order to bring focus to your subject, you have to have a certain amount of progressive focus where your point of interest is sharp, and the leading lines bringing you into the topic. Your previous works have been quite good in the past, and as it seems, you haven't been working with photoshop in a while, so I'm just trying to give you a boost. Hopefully you've come up with some stuff again before I get back with my new pc.
