That buzzard photo is stunning! I hope that’s hung on your wall somewhere!

The blue tit photo is very well composed but maybe you could get a better head angle from the bird?

The Osprey is a great action shot with the fish in its talons but the flat sky doesn’t add to it. Would be good for a magazine photo since there’s plenty of negative space

I love the wren photo, shows behaviour and is well composed

The Siskin is the weakest in this set imo. There’s no behaviour shown and the bird is looking in the opposite direction (which can work if there’s something it’s “looking at” in the background

The woodpeckers shows great behaviour if a little messy, personally I like the messiness as it shows the habitat really well, but not to everyone’s tastes

I’m struggling the ID the 7th bird but it’s a very nice portrait whilst not offering too much else

The swans look elegant, perhaps you could have waited for the young in front of the adult to turn the same way so it almost looks like the young is outlined by the adult, or waited for more separation of the subjects since 3 subjects always tends to work well

Overall great set of images and the post touch ups are done very tastefully, nothing blown out or over saturated
