I believe "Surfer Dude Fed" is the Nemoidian who says "two Jedi have landed..." etc....he's got a lame voice. REAL lame.
Anyway! I like the voice! It's at least a start...one thing I wonder, though, is if, forgetting about the stupid coughing, you keep the ragged breathing as the echo of Vader's trademark sound effect...I could see it either still being stupid or increasing the creepiness. But, hey, just throwing it out there!
