HI Paola.....Nicely caught pose!
I agree this image does look grainy.Is it a crop? Was your ISO a bit high?
The eye needs to be lightened and sharpened.
Hi Paolo Image is larger than allowed We can go 1024 If you need any help please let me know Also posting tech info helps out figuring what you were trying to do !!!
Excellent action and catching with a 600 not easy !!! Tech wise I would smooth out the bg and fill the large white area on the lower right, tends to attract away fro the birds !! Will wait for tech info !!!
