Got back to Tahki today and continued shading his fur. I put in darker brown, and then blue.The shadow areas definitely have more contrast now, and I think the blue carries. I might have to go back and tone it down a bit on some of the edges, but I might highlight first and see how I feel about it after that.
And while I had Blue Liner on my palette, I put some quick shading on Ezren's robes. I will probably go back and put a darker shadow in a few places.
