First Butterfly

This little fellow was stuck inside all morning sitting in the corner of the window frame and was moving slowly so allowed me a couple of attempts to get the shot.He seemed a little injured but he got lively a little later when we put him outstide and he flew away without any fuss.
The only thing, that I think is, wrong with it was not having complete focus due to his movement and using the window with so much light coming through although it did help fine tune the central portion of it. Oh....and it is a back blip
