Specially for all you Khorne fans I had put up a tutorial on how I paint up chaos space marines. In this process I used an airbrush to create the first highlights and finished off with a lot of wash work. I started by preparing the mini priming it with Chaos Black.
I. When I had my mini ready and primed I airbrushed it with Vallejo Air Dark Brown color. When the coat was dried I covered it with Vallejo Air Light Red but only from the front and the top of the model. I tried to leave the deepest areas brown. I finished with Vallejo Air Orange color sprayed only from the top finishing my pre-shading process.
GW Shade Reikland Fleshshade. I did apply the wash all over the gold parts and I infringed towards the armor plates.
GW Glaze Bloodletter. That made for a really smooth transitions. Unlike washes, glazes don't tend to leave borders of concentrated pigment when they dry off so they are excellent for this kind of job.
GW Shade Nuln Oil. I washed every recesses that connected the armor with the gold elements and also parts of armor connecting one another.
