This is Dylan Cole. He is a concept artist and matte painter from California. I've been a fan of this guy's work for years. You have seen his work in many movies like I-robot, The Return of the King, Alice in Wonderland, and Avatar among others. I highly recommend getting his training DVDs from thegnomonworkshop.com. You can find samples of his work at www.dylancolestudio.com
Hope you like it.
