Raven Guard Sniper Scouts and LSS (now with paint)
Although I enjoyed the previous two paint schemes of my Raven Guard & Raptor Scout Squads, I thought I'd try and something a with a dirty grimy feel to it. The Land Speeder Storm started black with white markings. (Really, I swear its true.) It the received a few dry brushes and washes and even a spray mist of thinned graveyard earth with the passengers and crew loaded to get to its final grimy state.
I'm considering touching up the lights and a few other details, but based on my experience, after enough time with fine dust, they just look like more of the hull.
