I wanted to paint something black so I painted the fire fox from Finnish mythology again :]

Its fur is pitch black, but it shines in the right lighting conditions and sparks in mysterious light when you touch it. Those sparks would fly to the sky and create the northern lights when its tail or sides hit the snow or branches as it ran. The Finnish word for the northern lights, "revontulet", literally translates to "the fires of the fox". It was hunters's biggest dream to catch one as its coat was very valuable and it would've made you rich and famous for the rest of your life. Stories say that their coats were used to lit cellars as they were safer than using fire.
