1. Overexposed, centered, not very interesting.
2. Overexposed, centered, birds are too far away and just too much going on.
3. Overexposed, crooked, what am I supposed to be looking at?
These look like iphone photos. Not that there is anything wrong with that, but if you're trying to get it to act like a stronger/better camera than it is, you're not gonna succeed. I use my iphone camera for more abstract work since I can't control the exposure or anything for that matter. (New iphone will have AF, and video!) I have the camera bag app, and toy camera app which both produce some cool effects on your shots.
Try to keep everything in one post. There really isn't a need to multipost. If you aren't sure how to post a couple pictures in one post, ask anyone will be glad to help!
