Lovely shot, in my opinion. I don't mind the light background at all, but kinda wish the yellow-brown part was not isolated in just that one area....it's not a huge flaw though. As for sharpness, I kind of like the very slight degree of softness but seems that most people prefer tack sharpness! I think you've got good enough focus that a pass with USM on just the bird will do the job.
Yes I agree with you Rene, the BG is a bit bright. A darker BG would enhace the light plumge of the Jay. maybe a little more sharpening of the Jay to bring out more feather detail. But a lovely bird that we don't get here, down under!!
Nice to see a relaxed Blue Jay (alert and excited seems to be the default for this species in photos). I like the front-on pose, too. I agree with Anita that it's the mix of pale and darker in the background that distracts a little. I would like to see this with all high-key background, but it's a lovely image all the same.
Hi Rene, I did a quick fix, used a graduated blur filter for the background, cleaning the face afterwards. Softened the brown spot in the background with the cloning stamp and sharpened. Effect exaggerated for illustrative purposes.
