This is the stage I'm at now. This is the side facing the camera, so replicating the prototype photo is key. Here I'm just drybrushing Windsor & Newton oil paints on the model, letting them dry, then wet sanding *lightly* with 1000 grit paper, rinse and repeat. The colors I've used so far are Raw Sienna, Burnt Umber, Yellow, White and Red. You can see two of the panels aren't really a perfect match for color and texture - they're still wet... more to come.
