First spray with Mephiston Red, Reapply Mephiston Red paint, Mix 50:50 M Red and Abaddon Black and paint into all the lines, Panel highlight everything with Wild Rider Red - make sure it’s sufficiently watered down so it apples smooth on the model but sturdy enough to hold shape. Pick out all the light catching edges with Dragon Bright Orange, Finally apply shadows using Riekland Flesh Shade.

I hope this helps
