Always interested in the bird shots..this looks like our Blackbird (which I think is called a Robin in America ??).
Well centred but unfortunately the sharpness is missing..possibly because of digital zoom being used ??. Good capture though.
Lacks - well a bunch of stuff really, other than a difficult moment to catch. I'm not sure that difficulty provides enough imapct to overcome the shortcomings of the shot however. Focus, detail, plasticity are all missing, and frankly it doesn't really call out for a centred composition - doesn't depend on it for its impact, if you see what I mean. 5 - for some sense of personality.
Some significant focus problems here. Nice timing on getting the shot; sometimes its not easy to make everything technicalyl perfect before your subject flies away. Keep trying - I'd love to see this one in sharp focus.
