The subject filling the frame is good; it creates drama and leaves no question about the message and intent of the photo.
The backlighting of the wings is beautiful. This is a photo about light, as much as it is about a butterfly.
I’d recommend burning the bright spot at the top left of the frame; it’s very distracting.
Also, the proximity of the insect’s legs to the bottom of the frame seems a bit tight; more space there would be nice.
