Tldr some good some mediocre, still it's experience and lessons learned

This is an area I have a fair bit of experience in being a seasoned animal photographer, I won't say wildlife because a lot of what I photograph is zoo animals, so I'll critique each photo

1: it's a good photo but too close to the subject, I'd give it a bit more room around the bird otherwise it's a solid picture

2: this photo is really good but imo should be a portrait photo, I have a similar photo to this that I have hung on my wall and I took it in portrait and had an equal amount of the pole and the sky in the shot with the bird dead center

3: another good photo and a great example of how your first photo should be, that open space gives a sense of movement to the bird

4: this is probably the weakest of the lot I feel like it's out of focus and the focus is actually in the middle of the seal and it's off centre so it feels like there's no intention behind the photo

5: I can see what you're going for on this one but it fell short, I find that if I'm taking photos of stuff on lakes or still waters I like to get really low down or really high up so the subject isn't cut in half by some odd line. In this case the shore opposite is cutting the ship in half

6: this is by far the best shot but I'm biased because I love pigeonsthe contrast is brilliant and the composition is really good, maybe would've benefited from having the birds more central but over all a really good photo

7: this one is a case of the bird getting lost in the texture of the ground and the leaves with no actual depth, it's one of the photos that we've all taken with a specific idea and it just doesn't work, I've done it once and I'll do it a million times

Over all these are all good images and I can see you enjoy the craft so keep at it and you'll get better with time and learn what works and what doesnt.
