Nice shot mate, could crop out the left a bit though and draw the eye in to Robin a bit. It is very difficult to shoot birds perfectly as you cannot move position without frightening them and have to use a long lens so shake is always a problem. It would have been good to have got down to the birds level a bit more rather than looking down on it but chances are you would not get any shot if you moved. I went out and tried to catch a kingfisher with a 500 mm lens the other day - saw them streak past but not a hope in hell of getting a cool shot. Will try again early morning one day!
