Dylan Cole has done matte paintings for The Lion, The Witch and The Wardrobe, Lord of the Rings – Return of the King, Riddick, Daredevil and others. He is also a conceptual artist. He does some traditional painting but works mostly digitally. The “Matte Painting” section of his galleries contains some of his professional work (arranged by project), but the stuff I found most appealing was in the “Sketches” section.
The galleries, thankfully, have an intelligent click-through navigation that makes them easy to browse.
