My final entry entitled "Green Trash"

A trailer-park dwelling alien cooks a meal while loathing the repairs on his crashed UFO. He fears he may never get off this rock...

Created with Maya, rendered with Mental Ray. Textured in Photoshop.
Items of interest: Particle fire + smoke, Particle beam, green radioactive glow on UFO interior parts, a little Paint FX work, character is fully rigged, and the mushrooms are edible.

(and unlike some other entries, it is actually 640x480 as requested )
