I decided to take some new pictures of this Cthulhu idol for two reasons. One, it's heading off to a new home soon and I wanted some snapshots before I pack it up. Two, my photography setup has significantly improved since I took the pictures in the original post. I'm still a crappy photographer, and I'm sure it doesn't help that I'm still using a Canon A-20 digital camera that I bought almost ten years ago, but the new light tent somewhat compensates for even those drawbacks.
The beauty shot. There are better Cthulhu sculpts out there, to be sure, but I like how "alien" this depiction is.
From the side. This view gives you a better feel for the proportions of the finished idol.
While there's a lot of room for improvement in my sculpting skills, I'm rather proud of how well the jade finish came out. After painting the whole idol with a base coat of dark green I stippled on two lighter shades of green to create the marbling effect, then coated the whole thing in a couple of layers of clear acrylic.
