The blue-garbed shadow warriors are actually an older paintjob. Drybrushing gloves is not something I do anymore, as can be seen in my more recent guys. I've got a pretty good generic middle-brown leather recipe which serves me pretty well now (Snakebite Leather, followed by a heavy wash of Ogryn Flesh, and a light highlighting with a Snakebite Leather + Vomit Brown mix), which you can see on the much more recently-painted red/brown-garbed shadow warriors.
