The setup is great - definitely looks like a scene from my bedroom as a teenager (although there would be much more smoke), but I'm not sure about the perspective. Nice job though!
everything looks typical 70s...except for her shirt IMO. and i think there's too much empty space at the bottom...could be cropped out, thus placing the model on one of the points of interest (i think that's what it's called. or whatever they call the point where two lines of the rule of thirds intersect.)
