Basecoat in Burnt Umber, and let it dry. Now use water and thin the paint down a bit, it isn't going to be quite one to one. You don't want your paint runny, but you want it thinner than it comes out of the bottle. Colors used are- Burnt Sienna, Raw Sienna, Butter Pecan, Metallic Inca Gold, and Burnt Umber. Use your Sea Sponge and work while it is wet with all the different colors til you get the look you want.
