Hey BMB,
Very nice series of shots.
I think you're doing very well - even if you're still learning
Just a couple of things for you to try - and see whether you like the results or not (and I'm picking on these shots because they're my favourites):
Shot 1) crop the bottom 3rd, which will put more emphasis on the boats and row of buildings.
Shot 2) Try taking the sky out completely and boosting the contrast just a little bit.
Shot 3) This is a tough call. On the one hand, a little more room around the tree and a strait horizon would be the standard response, but I like the crooked horizon in this. Perhaps just a shade lighter would help, but that's a minor thing.
Shot 6) a bit more exposure would have given you more detail in the darker feathers.
Overall, I like the contrast you're getting in these shots.
In shot 1, the contrast and saturation are great. I also like how the bank of the river leads your eye through the frame!
In shot 2, I like how the waterfall is surrounded by the trees. Gives it a feel of a hidden gem.
In shot 3, the contrast and colour are great. In this case I think the crooked horizon really works well and I love the detail you have in the water.
In shot 6, the fact that you caught 2 bald eagles is a treat in itself. I love the blue sky and how the eagles are flying in opposite directions. It's a very cool capture!
Cheers.
