Ok I know I have already posted a couple of names on this topic but I have recently discovered someone who's work seriously blew my mind. Her name is Soa Lee and she's Korean. This is the link to her site
http://soanala.com/eng/ I'd be interested to hear what you all think. The standard of the work on display is beyond anything I have seen for a very long time. She uses 3DS Max and photoshop for most of her work. Take a look ...I don't think you'll regret it!
