Here is the full process for my submission in "The Journey" 3D transport category. I wanted to create a ship and environment inspired by sea life around a coral reef. Modelled in Maya, cliffs done in Zbrush, rendered with Arnold. I did almost all compositing in Nuke as i wanted to get better at it while doing some photobash texturing in photoshop.
