If you get stuck thinking of that one thing to draw, a good exercise might be to flip the script, and spend 5 minutes writing down as many ideas as you can (like everything that comes to mind when you think of the beach), or drawing as many quick gestures as you can. Quantity over quality. Then look at your scribbles and see if anything jumps out at you.
