I really like the new single sprue charactors, so that's why I painted this guy up. Just a quick paint with nothing fancy. Simple and effective.
For the black I used my typical, base + highlight then wash to tone down the highlights. I suppose I could mix black and grey for the first highlights, but I think this works well enough. With black its often a good idea to smooth out the highlights with a little black to help with the transition. The same goes with most base colours, but especially with dark ones where the layer is quite a bit lighter than the base.
