I think this is more interesting than many of the nail shots we see here in the challenge. I do have a few technical issues though: IThe lack of clarity of the light and shadows on the wall detracts from this as an abstract or geometric design. The perspective shift of the radiator suggests that this could have been made even more interesting by shooting it from a more pronounced angle, say the floor. Maybe even tilting the camera. A large depth of field should have been able to capture the shadows in focus as well.
