Great use of DOF, details and BG. I would have preferred a slightly higher point of view to be able to see the legs. The whites have a slight blue cast and I might crop a bit off the right.
Very nice shot Simon, I agree with Axel, excellent DOF. I like the low angle, the colours and detail. The bird stands out nicely against the background. I was thinking maybe a slight crop off the bottom, but after looking at it for some time I think I prefer as is.
