This is about 1.5 hours worth of work. I refined my drawing on a new layer. Those are the black lines, and that layer will be removed in the final illustration. I am using multiple layers and the preserve transparency option. I’ve got the body as a single layer, the mouth/tongue as a second, the teeth as a third, the snout as a fourth, and the eyebrows as a fifth. To make the edges of layers match up (body/eyebrows/snout) I keep the ‘preserve transparency’ on, and also turn on the ‘pick up underlying colours’ option. then I smear the lower layer colours onto the upper layer. With pick up turned off, Painter picks up black from the ether, so sometimes you get black smudges near the edge of a layer when you are using preserve transparency. If you have preserve transparency turned off then it’ll pick up white. Why the difference? I have no clue.
The colours off to the side are so that I can keep returning to a specific colours and shades.
