I really like your stuff. You have opened my mind to a new idea. Can you picture the Bruce Springsteen album "Greetings from Asbury Park"? It is fashioned like an oldtime postcard. I don't want you to change too many of the elements that you have, I really like everything.
Can you make the people sitting on the beach a little more distinctive? They can be standing, a man & a woman. He can have a straw hat or a surfboard. She can be a little curvy.
