This guy also started a Kickstarter for a book called "The Road to War" that contained many of these doctored images. It managed to be fully funded, but is currently under investigation because people have made copyright claims. So please keep an eye on him and lets your friends and followers know. Thanks.
Seriously, my first thought was, geez, it looks so realistic!!! The perspcective is awesome! Every nook and cranny is texturized and shaded perfectly, and those eyes, those are some real looking eyeballs! Simply magnificent! A definite favorite!
