I'm almost done with this piece, some more shading, then I'll sleep on it (not literally) and see if I need to do anything more to it tomorrow night. If not, then I'll pack it into the frame and it's off to Salem on Saturday.
I've really enjoyed drawing these tentacles the past two nights, they just flowed out of me, so to speak. I find it somewhat easier to draw things that are not based in reality, you don't have to worry so much about whether or not they look "right," unlike, say, a person's eyes.
I'll publish the final piece next week, along with the steps I took to make it.
