So you should be, it's a cracker.........I'd crop it a bit tighter to make the bird more in the frame but looking at it it could take a crop no problem.
No no 2 is as it came out of the camera as is No 3, No 4 and No 1 are the only ones I had to play with slightly(exposure). Lighting was really difficult with the clouds, so I kept taking exposure reading from the grass as I know that is neutral. I'll have a go at cropping No 3
