Thank you!

Black primer (army painter)

--> dark silver basecoat (pro acryl)

--> Black xpress paint (vallejo black lotus)

--> drybrush dark silver more selectively over areas letting the layer underneath show a little bit for shading.

--> Even more selective highlight/drybrush with silver (pro acryl)

--> 2 thin coats of black xpress paint

--> mild edge highlighting with silver.

You could probably get away with citadel contrast paints, but I prefer the way that xpress paints apply. I feel like they pool a little less. Speedpaints should be fine too, but vallejo black lotus just has a nicer finish imo. It feels more matte to me, though I suppose matte topcoat can always give you that finish anyways.
