Here's Dagon's tail with the colors roughed in. I've glued it to the body.
I initially tried roughing in the colors with the airbrush, but it was not cooperating. There seems to be a clog in the nozzle that's keeping it from working properly. I'm going to have to take it apart and see if I can fix it.
There's some pretty sizeable gaps where the tail meets the body that I'm going to fill. Then it's just finishing up the tail pieces with blending, detail work, and highlights.
