ooo you are a very lucky young man!!
How to improve this image?
It is pin sharp - so not much room for improvement there!
I know this is hard because robins do not stand to order, but if it were possible for its head to have been a tad further to the left as we look at it so that slightly more of its eye were visible. Also I wonder if there was a means to avoid the slightly blown out section on its chest? Would it have been possible to stop down the iso to 200 - fractional I know, but.......................
My only other thought is whether using f8 might have brought the fore ground into focus which would then be less of a distraction.
Well done, though, Max!
