Nuln Oil Gloss over Yriel Yellow for the servo headlight.
The darker Sector Imperialis terrain needed more color, and Nurgling Green is that color. I also used this on the Deathworld trees and it's subtle but really helps tie the whole piece together.
The sector imperialis terrain sure does take a lot of paint, but it's very satisfying to see these come together.
