Like the smoke signals coming out of the beach hut in no. 3 ! Like the shallow depth of field and don't mind the people in no. 4 but think it would have been better if they had been walking the other way - down the beach and into the frame.
Thanks everyone, I think no.3 is my favorite. I wasn't sure about the people in no.4 would have looked better if they were slightly apart and holding hands. Bob you're right a gull would have made it an awesome shot
