The underwing pattern is amazing. Sharp and a perfect EXP. BOKEH and noise are questionable as suggested by Alfredo. Like the angle so as to include the far upper wing.

I would definitely use a soft brush or clone stamp on the right side of the frame to even out the unfilled areas a bit. For my taste, the bush is too hot - there's just too many blown highlights for me in that area. I do really like the butterfly - your details and focus are excellent.
Agree with the comments above. The butterfly looks great. And that background has enormous potential. Soften it and reduce noise then either crop out or clone in that lower right corner.
