stromtrooper helmet on an unknown planet

Hi, everyone, this is my latest personal project.
I decided to create this project for my portfolio, as well as to test my performance in realistic image rendering.
This video features a stromtrooper helmet on an unknown planet.
I use substance for the helmet texture, Maya for the fluid simulation (fog) and renderman for the rendering, I hope you like !

test sand simulation, with granular (realflow)

test 2, sand, granular (realflow)

I wanted to show the helmet in space, after a space battle the helmet is lost in space, before spitting on the unknown planet. The planet in the background was done on photoshop using photos of the earth taken from space.
