A little light on the side, please

I have been under the weather this weekend and haven't been able to do much in the way of shooting.  So, I thought I would keep it simple today and illustrate the concept of side lighting to add texture and drama.

In the photo below, the setting sun is low in the sky, creating long shadows across the snow.  The shadows of the tree branches trace the contour of the slope by the old stump, bringing out the detail of the terrain which wouldn't be as obvious with flat or overhead lighting.
