You got the tones and the mood right, but, to me, the pose of the dancer looks quite unnatural in this frame. Perhaps it's because of the missing back side.
Ahhh I am quite familiar with his work. This is a good adaptation of his "ballerina" pieces. The tones are good with an improvement with an adjustment of levels. One word of improvement is to allow the hands and foot to be in the frame of the image as opposed to being "cut-off".
this image has a nice grayscale 2 in something Imogen also has in most all her images but it lacks a real draw. nothing grabs u in it the way her images draw u in, i think to a large degree this is beacuse of the subjects pose and the framing of the shot itself. also there is no real sencd of connection with the viewer no common ground to meet on, in your image the viewer must ingadge the image or not look at all, in her images the image will ingadge the viewer drawing u in with a common ground. most offten a pose which instantly fascinates the viewer with its form and stance to the camera.
this image lacks that quolity and in the case of Imogen (i feel) that is core to the image. GL
