If I could offer some feedback, some thin, coloured washes on the armour would take it to the next level.
Trust me, it's washed already. Just washed out by the sunlight
The bright silver details are chaos black, then boltgun metal, chainmail, mithril silver & black ink inbetween the colour layers.
The darker parts are a chaos black undercoat, a two parts chaos black to one part boltgun metal base coat, a boltgun metal highlight then a wash of black ink.
That being said I keep thinking he's not quite finished yet and needs some finishing touches. I'm thinking dark mud stains on the bottom of the cloth but something dirty on the armour as wella s the dark oily greasy look might help. Thanks.
