Establishing the background
Here I continue to use much the same mix with a little more Ultramarine. I'm just roughing this cave out and thinking that I might bring some foliage into the right hand side and perhaps coming down from the top to the painting. For now it's enough just to get the darks in place and that allows me to consider what degree of detail I want to put into the cave and the surrounding area. I also begin to indicate the edge of the floor of the cave. I'm thinking that I want to suggest that the animal is fairly high up a cliff face, not at ground level.
