Agree that #3 is the best, because the stones lead into the lake, it's just grabs your eyes and pulls you in. The blue in the other two pics is WOW! Such intensity but agree, they don't quite compare to the 3rd one.
I think that the third one is excellent. Everything in the photo from the rocks and water to the hills and dramatic sky just draws me into the photo and makes me feel as if I am there. And contrary to the above comment, I really like that you included the red rock in the photo. It would have been a completely different photo without it and I don't think I would like it nearly as much.
