I had the opportunity to work with many other talented artists at The Coalition on ACT 3 - Sand Overworld, the images are from several areas in that level.
My responsibilities for this level were: Creating proxy meshes for the environment art team, sculpting/painting the terrain, set dressing, and final art polish (decal placement, vertex painting).
Here are some of the talented colleagues that I worked with on The Sand Overworld:
