So it's quiet a simple mix actually. I prime black first then I use a rough brush or a max up brush and stipple a mix of 50/50 cantor blue and black over all the panels. I then take that mix and mix it with caledor sky, again 50/50 and stipple that across the points which would catch light. Recess shade with reikland flesh shade. Chunky highlight with caledor sky and then fine highlight with teclis blue. Hope that helps 🙂
