so, metals, possibly one of the harder things in this hobby to get right and something ive always struggled with. However, there are some great articles out there on metallics and non-metallics but i'd like to highlight what i would consider to be the best metallic tutorial there is and it's by Automaton (Sebastien Archer sp?)
here is a link for anyone that's interested: http://www.mainlymedieval.com/ozpainters/viewtopic.php?t=878
Now i'm a huge fan of this guys work and have seen a few pieces "in the flesh" and trust me when i say he really is a painting master. So i followed his tutorial on how to paint metals but with my own recipe.
anyway,,,,pictures would be a good start before describing the method.
Basecoat : GW Boltgun metal
shade1: GW Vomit Brown
shade 2: GW Bestial Brown
shade 3: VMC Cavalry Brown + Black
shade 4: VMC Royal purple + Black
wash 1: Boltgun metal (all over to bring back a metal texture)
highlight 1: Chainmail
wash 2: GW Leviathan purple (towards the shadows)
wash 3: GW Sunburst yellow (towards the highlights)
highlight 2: Mithril silver
i hope thats helpful to someone :)
