Some great captures there, the cloud gives a good and different type of contrast to a sunny blue sky. #3 and then #4 probably my favourites.
I saw the Blue Angels in SF one time but they packed in after about 2 minutes because of low cloud, they said, yet there was nowhere near as much as you have there, neither was it as low. You did well!
