Here is the Knight Errant, the Legion of one, Nathaniel Garro.
I have finished Nathaniel Garro, and here is how:
Undercoat him Black first. Then with an airbrush I sprayed a layer of Iron Hand steel. Then did a Zenithal highlight with the airbrush of Mithril silver.
I then purity sealed the model to dull it.
Then to portray that the gold curiass and eagle were slightly old and ornamental, I used Vallejo old gold. Shake well and very very regularly.
After this stage I raised the model up with layers of Iron Breaker, to Mithril silver. Then a targeted recess wash of Nuln oil before Tamiya chrome Zenithal drybrush and edge highlight.
The text on the bottom of the shin and the whole sword is grey Knight steel (Forge World) which gives a great blue / silver flip.
Beneath the each level of the wings I did a Druchi violet wash then added a edge highlight on the highest lines of Mithril silver using the side of a brush.
The gold was washed with a slightly thinned Agrax Earhshade.
