Creating an interesting scene, artistic perspective

here is an image im trying to make a little more interesting, but unfortunately i do not have any artistic perspective. If anyone can give me suggestions to create and interesting scene around my character, he is a dinosaur looking turtle… you decide what you see

trees, rocks maybe a mountain or volcano in the distance
or just a little pond with some lilies some pebbles lying around some verns, stuff like that
or just a beach with the ocean…
