Praise the mobile phone for WIP photos... as basic as they are. The guard have been given a moderately heavy drybrush of brass, but trying to leave lots of black shadow throughout.
Trying out the verdigris technical paint from GW (Nihilakh oxide). This is very liquid and seems to get a decent effect running into the crevices. Strictly speaking it's not how oxides form, but not bad for a quick look on a miniature.
