Very nice job!
The hood seems a bit over burned. Lighting is tough though. I can't seem to find this mystic GI_Joe thing. I checked out highend_3d and there is nothing in the downloads sections called "GI_JOE". There are a half a dozen GI shaders but I don't want to start randomly cluttering up my Maya setup with script files that might affect my configuration. Since I don't know a lot about installing and removing scripts I have been trying to work with the base software. Don't want to try to install something then get goofy results and not know if it is something I am doing or something the scripts I have added are doing.
