Iggy makes a great point - very hard to critique 5 images at once.

But in general, the bird shots are better than the people shots imo.
When photographing a large group of animals there should be a clearer focal point imo. Shot 1 is sharp and somewhat interesting but it would be better if one bird was doing something a bit more special. shot 2 is better than shot 1 in this regard.

The people shots I'm afraid are a miss for me as they are basically just staring off into space or somewhere unknown. There is no interaction with the viewer and their gestures aren't that interesting imho. hope that helps somewhat - and it's just an opinion.
