Here are a few Unreal 3 levels I made for my senior project when I got my Bachelors in Game Art and Design at The Art Institute of Phoenix.
The first room was a concept for an OmniSynapTech Corporation star mapping facility. It's here that they forge the Navcom black boxes out of stem-matter that allow starships to quickly travel through synapse gates to other star systems.
The Super Pac-Man machine I modeled in 3DS Max and painted in Photoshop using references I found on eBay. The original was pretty old, hence all the grunge.
The island level was loosely inspired by a combination of H.P. Lovecraft's Shadows Over Innsmouth and the rocket shelters they have in Israel. I had noticed that several of the shelter references I Googled had beautiful murals painted on the sides.
