It's difficult to see in the picture but each element is 1/4" thich and sits in front of the layer behind it giving a 3d look.
There is enough room on the base to sit a candle if you like. The candle high lites the 3d effect by casting flickering shadows.
Using different species of wood gives the project a great look. In this example I used Walnut for the sky and base. The cowboy is Peruvian walnut. The cactus is Yellow heart and the dog is Bubinga. The mountains are Maple.
Enjoy the pattern.
