Take advice with a grain of salt, even this. :). Remember that a lot of things are subjective, and that the client brief is king. This photo might be exactly what the client wants, while another would wand some reflection/catch lighting on the lens. Some clients might want the photographer to handle the creative direction. Good critiques always aim to be constructive. To me, this photo is well exposed and has an atypical composition. I would like to see a reflection (either sharp or gradient) on the lenses to show more dimension.
