I really like the lighting here. For some reason, it draws me into the image and the left half has almost an illusion effect going on with the slinky. Really like this.
I think this is a really nice clear well focussed shot. The only area where it loses some marks from me is that it is meant to be shot in an 'interesting and creative way'.
While the technicals of your shot are great, and the overall image is pleasing, the slinky is just doing what slinky's do rather than anything different or creative.
