Shamelessly adapted from Wiltrichs' excellent painting Ragnar series on YouTube.
The model was primed black, so I gave the fur two or three thin coats of Wraithbone . The paint is intentionally watery, as you're building layers and you want it smooth and don't want to clog the layers!
Next, I applied a couple of thin coats of Zandri Dust . As with the previous layer, this paint is about 50:50 water to paint. Move fast, big brush, always let it dry.
Leaving a few layers of fur, add a couple of thinned coats of Gorthor Brown . The first layer can be slightly wider than the second layer to tie the Zandri in. Or, think about the shape you're going for and sketch that pattern in. (see the difference between the leg fur and the thicker back fur)
Next, leaving a similar width of fur, apply thin Rhinox Hide . Again, first thin coat blends the previous layer, second deepens the Rhinox.
Finally, apply a stripe of Abaddon Black . As before, thin, and use the second coat to build depth.
Glazes and Shades
At this stage, I review the pattern and apply very thin layers of each colour stage to blend the transitions. It's getting on for a 60:40 water to paint ratio.
Once you're happy, an all over coat of Contrast Medium mixed with Agrax Earthshade (3:1) all over ties the layers together and adds a soft shade to the areas of Zandri Dust too.
Use a thinned Ushabti Bone and the side of a brush to highlight each strand across all layers. The same highlight colour works, as with it being slightly transparent, takes a little a slightly different hue over each colour transition. Draw down the strand in the direction the fur is moving, so the most paint is drawn to the tip. Some times you will need a steady hand to use the tip of the brush. Don't rush this stage, as it takes a lot less time than you think!
On just the Zandri Dust layers, add a highlight of Wraithbone or Screaming Skull (or even White Scar ). Again, thin paint, and just dot highlight finest edges!
Using the same Contrast Medium and Agrax Earthshade mix from earlier, apply another coat all over. This evens the highlights now.
Add a bit more Agrax Earthshade to the previous mix, and shade the deepest recesses. I also lined in folds etc to add contrast.
Re-establish the very finest edges with the top highlight colour.
