firstly, the original photograph is a wonderful one. I like the use of the situation and the settings.
Secondly, I prefered the vertical composition, cropping the rather disturbing background behind the butterfly. I also prefered to keep the flower in the frame, that gives this image a certain merry-ness!
2. Gamma correction

I hope you like it, although I did not take your permission before processing it, I am sorry :(
Beautiful photograph again! :)
