Delightful shot, beautiful colours and excellent detail. Had it been mine I think I would have taken a small step back to include the flower head and give a little more head room. I like the OOF blooms in the background.
I also would have stepped back to include the whole flower head - you can always crop it in pp! I also think a tiny bit more room up top would be nice. What you do have here is well exposed, the yellows are nicely controlled and the butterfly is focused and beautifully seen. Wonderful image!
