Comic intro image - whose arm is that?

In the image next to the comic introduction/summary area (“Tamberlane is a webcomic about a clumsy bat and her very human baby…”), whose arm is on Tamberlane’s back? It looks like it should be Belfry’s, but it’s colored like Oakewood’s. Or maybe I’m misinterpreting the shading.

Heh! It’s Oakewood’s right arm, just kind of drawn at a very awkward angle. Good eye!
