I was really sure I'd posted these ages ago, I found them in my Photobucket folders, I'd certainly posted them on a forum as far back as Dec 05. I wouldn't quite call them Matte Paintings, they're more Photo Montage work done in Photoshop with a 3D Model thrown in. You can see the pics below that went into making the 2 top pictures, most people will recognize Vasquez Rocks, seen in numerous Hollywood films and TV shows, in fact IMDB lists 183 productions that have been shot at this location.

I was unsure about the wall in the shot so I did 2 versions of the pic, the wall was a quick 3D model that I rendered in Vue 5.
