These represent the 'next step' I took in polygonal modeling quality. I was learning UV mapping, and how to better use the tools in Maya 5.0 PLE. The result, was the damage amp base pictured below.
After a long break while the map was waiting for final release, I had switched over to Maya 6.5 and had gotten comfortable with UV mapping. The opportunity came to do a little more work on the map before release so I decided to create custom cliffs, which are also pictured below.
