How I resolved the problem...
Can you imagine a plain ocean with no waves, a beach with nothing there, a sky with no birds or clouds? Not me. That is what the owners said they wanted in the beginning. As I began to gain their trust, they began to allow me to add more things into the mural. They loved the end result. I would have liked to add some more tropical trees, plants, more animals ,etc. but, they liked it as it was.
