I've got a special project that will take a few days. It's a poster of Godzilla wrecking a city. This is the tracing and contour drawing of the basic ideas of the poster. I've erased the sketchy thumbnail art and guides, since those lines are just very rough anyways. Primarily, I used as a guide a picture I had assembled in Photoshop of Godzilla, the buildings, the train, and the roads, all culled from reference photos I found on the Internet, mainly from Japanese sources. Then I more or less just traced the various elements into layers in my drawing program. I used Photoshop to alter and correct the perspective.
