This is a beautifully shot photograph, the first thing I noticed was the composition, pose, light, etc.
The film, development etc. almost seems secondary to me (and I don't mean to shortchange that part at all) because it's the idea I notice first. Yes it's sexy but sexy because of the light, etc. (although she is quite beautiful too)
Agreed, it is a striking image and the light is certainly part of that but so is the POV, the fact that it has been shot from a low viewpoint. That, to me, helps to set this image apart.
