What a great title, Moonrise Watchers on Sunshine Beach; quite the play on words there Maris.
I too think your portrait view is the right choice, I'm particularly enamoured by the three slightly lighter rocks on the creek/river and the lighter patch of sand; they give the overall a bit of a lift.
Good idea to get away from the flat beach area, nothing worse than being used as a conduit for an electrical circuit as it travels up through your feet and legs then exits via your shoulders or head towards the arc coming down through the troposphere.
