These look pretty swanky bud....just finishing off 9 mounted troopers myself..though Artizan. I use / get a similar effect on chesnuts but I use old GW dark flesh highlighted in bestial brown and given a simple wash in nuln oil. Works a treat.
I do like these figures though...just a shame they wount mix in too well with the Artizan. I have just ordered a pack of apaches from GM...more scope to match them in with my others as they are more irregular in appearance...though not sure how they will stack up height wise with my Black Scorpions...
I may be tempted if he brings out a couple of cavalry wagon riders though....hint
