The last one is my favorite, very good composition!
1.The light house could have been a bit closer if not more. If there were some more pretty or un-normal cloud formations then at the distance you were at would have been good, but since the main focus is the light house then I would have steer a bit closer. But it is still a very good looking picture.
2. You might have wanted to crop down the top and bottom a bit more, kinda left a bit of dead space.
3. If your goal for this picture was to show the steepness of the ledge nicely done. How steep is that by the way?
4.Like is I said above this one is my favorite, don't have much to say about it.
