Spent most of the time working on the lizardmen. I was shading the skin.
I haven't done a lot of work on their heads. I'm using a color scheme I had on a previous lizard man, and when I went back and looked at the photo, it turned out I'd made his head read and orange. Here's the model I'm using for my colors:
So, the head, crests, and texture on the arms and legs will be going to red/orange.
