This photo has a nice airy feeling, very appropriate for the subject. Color rendition is superb, and the bokeh (quality of the out-of-focus background) is great. The insect is captured in a great pose, with the nearby stalks adding context and interest without distracting from the subject. But the stalks near the top of the photo with the bright light compete for the viewer's attention; cropping them out would focus attention better on the butterfly.
The butterfly looks in focus, yet is lacking in sharpness. I think the cause is jpeg artifacts, which are prevalent. A higher quality setting would have eliminated most of them and probably improved the overall clarity. But even with this minor flaw, the photo is very pleasing and beautiful.
I know how difficult it is to shoot those stupid butterflies. I spend some day's of my holliday chasing them with my camera...
Got home, best picture was NOT by me, with my far to expensive DSLR but my son's with his 2 mp Canon a40 :-( Very nice!
Nicely done. I like the vague green background as a contrast to the orange. I might have cropped it differently. Not sure you need that sun up there, so far from the center of attention.
