I sadly didn't get to work on this show much as I was up at Leavesden Studios working on Fast & Furious. This concept was for a ship that could stack up when not in use. When detached, the ship was used for transporting heavy containers using two heavyweight, retractable arms. These could rotate through the whole 360 degree circular area for maximum reach and potential.
This was created in Zbrush, rendered in Keyshot and completed in Photoshop.
