Ilmarinen forging the Saampo
Here's an earlier painting based on the Kalevala, the Finnish National Epic, of Ilmarinen forging the Saampo. One of the great things about Acrylic paint is the wonderful eye watering combinations of color you can come up with. 

The background is done with acrylic paint watered down and poured on the canvas. Acrylic is extremely versatile; it's a good idea to play around and experiment with it, who knows what you can come up with?
