I'm one of the volunteers from #CRPhotography here to give a critique upon your request! So here it goes!
I must say this is a very excellent photo, in terms of vision and originality I can honestly say I've never seen anything else quite like this photography!
I think what really makes this photo work though is the use of contrast. The darks and lights bounce off on another with a perfect balance. In my personal opinion, this makes the photo very intriguing to the eye.
The only that slightly bothered me was the fact the left wing (right wing looking at the photo) is clipped off by the edge of the photograph there. I would try to capture the whole of the butterfly. Otherwise though, I think it looks really great!
