There are simply too, too many pictures here, with such a variety of issues to address, to even start trying to give C&C on.
So instead, I'll issue you a challenge--an exercise to help train your eye--YOU pick what you believe are the two BEST photos from the selection above, and just post them instead. And if you really feel brave, tell us at least one thing that you think makes the photo good, and one thing you think may be an issue with it.
