Hi Carlo. As Allen noted - please remember to include the shooting specs with your post. This is a nice specimen captured at a good eye-level shooting angle and facing just slightly toward us. I like the even light, the exposure is right on, you have good overall sharpness, and a pleasing background. My only wish is that the OOF blossom in the LR wasn't there so we could see more of the flower the butterfly is feeding from. Overall, this is very well done.
