I found this on the net.... these are fan art... i bet that what you see here... the look of vader is a lot better than the portraial of vader that the movie will have at the end....
i like this drawings very much http://chucks888.freeservers.com/starwars.html
i like it, but its doesn't make sense, unless thats supposed to be based on Anakin shaving his head before the accident. I always thought the head shaving was simply a health issue, wearing that helmet all the time sorta kills the need for hair. But the suits cool, very McQuarrie, who I wish they'd have made better use of in the PT.
