Adjusted the curves.
selective sharpening on the wings and eye using the sharpen tool - I much prefer this method as you only need a hint of sharpness. Too much and the whole thing loses the sense of movement
Used the saturate tool on the beak and the eye to boost the colours
duplicated layer
Gaussian blurred the duplicate layer
set layer properties to multiply
Cropped image
Darkened blurred layer using levels
Used large soft edged eraser to remove most of centre of blur layer to create vignette
final gaussian blur on blur layer to soften vignette
Each to their own of course - but I do think the shot needs to be about the bird or the landscape - I think the new crop makes it more about the bird whilst the original crop is a little undecided for my taste.
Of course as always - I may be wrong
