Yes Alexander, a beautiful insect! You have made the insect really stand out from the nice BG. Nice sharpness and the exposure is right on the edge! TFS.
Very nicely done, Alexander. Apt use of flash. Beautiful BG too. A minor improvement: you may crop the cut leaves at the bottom. A bigger improvement would be to crop about an inch on RHS and 1/2 in at bottom to shift the butterfly to right. As it is facing left, moving it to right would enhance the impact. TFS.
I agree with Ramesh - more open space on the left for the butterfly to "fly into" would strengthen the composition. You did a wonderful job getting great detail and colors in this image - it just feels a little too "centered" in the frame.
