Pic's a bit small to be able to see much. I think I see some chromatic aberration around the stairs and the pipe (CA being most easily seen as that greenish fringing around the outlines of the hard-edged objects). She looks very attractive. The composition seems to have about half pretty girl and half fire escape steps, which doesn't seem quite like the most-favorable allotment of girl-to-environment. But whatever. Did I mention she's attractive? And has great makeup? The watermark seems quite large, especially for such a small photo. I think this would have had more impact if she'd have been framed with the camera in "tall" mode, so as to not crop her off at the mid-arm and elbow junctures.
