Hi James,
Welcome aboard. I checked out your gallery at some length today. I agree with Jeff that it is typically easier to ask for critique on individual images as opposed to a gallery as large as you presented. However, that is not to say that it cannot be done, LOL.
OK. I think that instead of focusing on what I don't like, it is easier to talk about the things I DO like.
On Page 1, I like the larks the most. Nice colors, well exposed, and no distracting backgrounds (though there were a few times where things could have been more level). I also like the flying night heron.
On Page 2, I like the Great Blue Heron at Bear River Refuge (though again, there appears to be a leveling issue).
Page 3, I like the burrowing owl on the first row, and the short eared owl flying (the first one, where it appears above you).
Page 4: I like the Canadian Goose photo a lot. Nice perspective.
Page 5: I think the Yellow Headed Black Bird is very nice - though you are pushing the edges a bit with the exposure. It looks like some of the yellow is a tad hot to me. The Osprey flying is also quite nice.
Page 7: I like the Franklin's Gull shot...though you may want to consider trying a bit of shadow-highlights to bring out the shadows a bit.
Page 8: I like the house finches...particularly the ones without the distracting backgrounds.
Page 10: The morning dove photos are nice. I see many of them here in the City.
Page 12: Whatever the bird that is 'by popular request' is a nice photo.
So, in short, what I am looking for. (1) Clear, well exposed subjects. (2) No distracting backgrounds. (3) Depending on the bird, I don't mind necessarilly that photos capture it's backside...however, I prefer frontal photos.
Thanks for sharing!
James
