Cas is a firm believer in quiet time.
Artist notes: Cas taking his quiet time a bit more pensively than usual. Likely because he's been downgraded from the Pyrenees to Bobby Singer's backyard.
Wacom tablet, Adobe Photoshop CS2, 5 or 6 hours. Mostly an experiment in actually drawing a background. Bare trees and chainlink fences are not worth the effort. (Also, scattering did not crash the comp this time! So huzzah, Cas gets his scruff back.)
