Fanart: Crowley's snakey bits

I'm taking advantage of a few unexpected extra days off to work on some fanart. This was inspired by chapter 5 of Chamyl's "Not That Bad, When You Get Used to It". The fanart is only slightly NSFW (Crowley's naked, but there's nothing on display), the fanfic is definitely NSFW.
