I really like the second one, but I made some changes. I cropped to get rid of some of the distracting branches below. I changed the B/W contrast to really bring out the tree limbs and expose the birds better. Also I did some touch up to get rid of a black spot (maybe a bird?) and a light spot on a branch. This is quick and dirty, but you get the idea.
The dog is sweet and I am a sucker for animals. But an ISO of 1600 adds noise to this photograph. Grain would be nice for an feel but not digital noise.
You are most welcome, that's why we are all here. To learn to see things differently, even if you don't like the suggestions, it forces us to take a look at the way we do and see things.
