Ok I'll start-
Its way over exposed and the feather detail is lost as a result, Its also out of focus and very noisy
Faster shutter speed and smaller aperture will help shot like this - not an easy subject to shoot to be fair - the bright white fools the meter on your camera, something you
need to be aware of and compensate accordingly
heres one of mine as an example of white bird shooting ( Great Egret) f10 @1/1000th sec- ISO 800

All up for advice and constructive criticism. it was literally about the four/fifth photo id ever taken so its a massive learning curve trying to work out what does what. Dont want to use the auto function.
