There's an interesting article about the work of Philip Straub, digital painting master on CGNetworks.com:
Welcome to the vibrant universe of Philip Straub –filled on the one hand with meticulously detailed visions of the bizarre, dreamlike, and unimagined and on the other with though-provoking contemporary works. From these to concept design to imaginative illustrations and fantastically-lit digital paintings, Straub's work is rich and stunning. Lisa Thurston interviewed Straub to find out more about the mind behind the art and the strategies behind his career success.
Mr. Straub's concept art is fantastical an incredibly detailed, but I was most fascinated by the contrast with his more personal work such as Political Bondage and Faceplates.
