Vessel.
Just doodling last night and wanted to watercolor this, but couldn't find my watercolors so I went a little crazy in the photoshop. Oh, burn tool.
I loved the wingy silhouette when the angels get snuffed out of their bodies (I guess that's what happens), and wondered if the same could happen when they bamf their way in. So this is just-vessel-ed Castiel checking out his new digs. I wanted the wings to go with the graffiti but I think my aformentioned abuse of the burn tool messed them together too much. Eh well, mostly a light/color study, I still want to watercolor it.
