Underwater Starfish Render (Updated)

A few months ago I posted a render of a starfish I modeled with some coral plants and a sand texture on a plane. I decided to go back and add some underwater caustics and make the scene look a bit more realistic.
Below is the final render:

Correct mesh on starfish, it it has more than one flat surface and color, the same for corals, they have different sizes, shapes, materials and placement, add more variety to ground, try to use one light to simulate sun, use references and you will be nearly there
