Thank you Tb0ne. Please continue to use the art in my sketchbook for inspiration. With regard to the latest sculpt, and this may be a limitation of the software you're using, but he needs deeper furrows in the skin if you want it to be accurate. The impression some witnesses have is that these beings have "twice as much skin as they need". There should be folds of skin across the bridge of the nose as well. The nose should also be less human looking, as if pushed into the face and stretched horizontally. It is "wide and puggy looking". These beings, in some cases, do have human-like lips, but the mouth is very wide. I think it should be wider than you've shown it here. There are variations, of course. So if you get close, one could make the argument that you've accurately represented a variation no one has described yet. I would also make the back of the head more squarish, in keeping with the front of the head. Not everyone describes the head like that, but in the case I'm thinking of, it's kind of like the whole head is a squished cube. In most cases, they actually wear monk's robes with a hood, so people don't describe the exact shape of the top of the head. The eyes do bulge out like this, but they should be more deeply recessed under the brow ridge. Again, it's just a question of how accurate to the descriptions you wish to be, or whether you'd simply like to use the descriptions as artistic inspiration.
