My second set of recently painted terrain is the Crashed X-Wing set, a more recent release. The model was painted similarly, with hand-painting on the X-Wing and R2 droid using base paints, then highlighted with contrasts. My home made dark wash ties all the pieces together again, working well for the size of the model.
The pilot was previously painted, using a collection of contrast paints alone. Not entirely happy with the face (it ended up with excessive shadowing), but it does really stand out against the rest of the terrain.
