I like the concept. The posing is good too. The images are let down though, by the fact that lighting has overexposed the skin in the shots. The skin (soft) vs rack (hard) is a nice juxtaposition, but the lighting detracts. A striplight would give the same effect along the body, but with more light control and soft shadow edge transfer.
I really like the first and the last one.
I have to say I don’t find the lighting too harsh at all.
I think it has a very dramatic industrial feel which works well with the metal of the rack.
I would have prefered in the last one though if the sides of the rack were at the edge of the frame like in the second one.
They make a good border.
I like the poses and the lighting! But the optic angle of the chosen lens seems too wide for me, you can see you’re near her and you can see already a little perspective change. Further, as you have the right lighting now, challenge your creativity towards the composition. The chosen frame of the pictures is very narrow so she is looking out of the pictures now. More space to the left, perhaps even with a second empty rack on the left, will not only create a better balance in the composition but you also will emphasise more the emptiness of the racks…
To avoid the perspective change you might use a larger focal length here as well (if it fits of course in the room!), the total frame will look more flat so you can create more tension between the strong and straight shapes of the racks and the bodyshapes…
Hope I could be of any assistance here for I’m only a Dutch nature photographer 8)
