I love these - the composition is exceptional. So many people do such close ups (which in themselves are great) but to me it always looks like the bird doesn't have any place to go. These are beautiful and still close enough to see bird details. Me? I can't get any good ones so admire those who can.
I love close ups but sometimes I think it's better to back off a little a have a more natural surrounding/framing. Also, more natural color might be nice. I have no luck with birds so congratulations on that!
