On the left we have a GW blood red jacket, shaded with Vallejo sepia ink. The collar is Humbrol 29 matt dark earth with a matt 64 light grey drybrush. Trousers are Humbrol 25 blue with a dash of white added for the highlighting. Hair is Humbrol 93 desert yellow with a Vallejo sepia ink wash and Vallejo bonewhite highlights.
The other has Vallejo charred brown trousers and Humbrol 93 desert yellow jacket, both washed with Vallejo sepia ink. At this scale, the original result was too subtle and just blended into an overall brown when viewed at normal gaming distances, so the jacket received a lot of brybrushing with desert yellow and then with Vallejo bonewhite. The collar is Humbrol dark grey with a light grey drybrush.
