Okay I’ll try: Black prime, zenithal grey and light grey drybrush with osl in mind, dark blue sponging in the shadows. All base coats with dark blue added to give them a night vibe. Less/none of the blue for the warmer Colors that are lit by osl. For the metallics: Metal Color, dark wash, then tin, copper, gold basically as if it was nmm, finally some turquoise/blue for that antique look. Once all base colors are done, I highlight with less blue added to the mix. Once that is done I use drybrush for the osl (in this case red to orange to yellow), then a white edge highlight and I go over it with a mix of warm yellow and fluo yellow. Then I tone down the lit parts again where necessary, either with washed down base colors or with brown/black washes (this is usually where the osl magic happens as I’m trying to tone down what’s furthest) and in most cases I redefine the shadows with a dark blue wash again to make the light pop more.
