Nice shots Kevin, I really like the second and third ones the most.
It is funny in the context that many think that great images are all skill where the truth is: It is skill plus luck. Joe McNally says that many of his preplaned shots were changed as soon as he got on the set and saw something different, like natural lighting and so on. He also goes on to say that a lot of his finals were shots that were pure accident, still I know that the skill has to be there but compositions do have a tendency to sneak up and reveal themselves. It just takes the willingness of the photographer to stay humble and go out of the box.
