Start as described in the previous part, doing the thin Burnt Sienna layer, then using tube texture paint and carefully brushing it, do a realistic black and white painting with all the details of your subject just using Ivory Black and Titanium White. Let that "grisaille" or "dead layer" dry thoroughly. It will look like a black and white photo in a way, very detailed. Then start mixing oil with all your colors, using them very thin, start painting over the grisaille layer. Covering the black and white painting with various transparent colors will let the light bounce back and forth within the dried layers and give it a unique luminosity. Only slow, heavily layered colored pencil rendering comes close to the effect. It's one of the things oil painting is famous for. You can try this method if you have a lot of time to let each glazed layer dry before doing the next. But if you don't want to take that long, just let the grisaille dry, add a bit of oil, paint over it in the right colors and add one final glaze when that layer's dry. You can get as elaborate or as simple as you like with oil painting.
