Thanks mate. The overall paint scheme was brush-painted, with a mix of the two colours on the edges of each stripe (example, Red brown and sand) to give a feathered, sprayed look. Dust and dirt was dry brushed where needed, then the whole model given a dusty look by dry-brushing overall with a very thin, light grey mix. The scratches on the side skirts were done with a pencil, as was wear on 'sharp' edges, such as stowage bins.
