I see many submissions here on dA that are of the same subject matter, but this image is an absolute visual delight!!!
Your vision is displayed perfectly managing to capture such complimentary colors between the butterfly, flower and background. This really adds to the eye-catching appeal of this lovely capture.
Like I mentioned above, originality is lacking some what ONLY because there are numerous photograph's on this site of the same subject matter (butterflies, flowers, etc...) However I really enjoy these types of photo's and this is a splendid one to behold.
As far as technique, I think this deviation shows great aptitude of your skill level and masterary of macro/nature photography. I love the significant details of the butterfly, its markings and even the texture of its wings is apparent. Which by the way is so much more pronounced in larger view.
Overall, in my opinion, this creates a beautiful visual quality--highlighting mother nature at one of its best. Well done!
