When the sun is low, there are five types of lighting that you have available to you. Light can illuminate a subject from the front, the side, the back, from a three quarter angle, or it can create transillumination where a translucent object seems to glow from within. In the example below, you see an example of three quarter lighting.
One thing to note about sunlight when it is low to the horizon is that the contrast is reduced. It’s significantly lower than when the sun is higher in the sky. The lower the sun is to the horizon, the lower the contrast will be. Look at the shadowed side of the great gray owl’s face and you can see detail there. This picture was taken about forty five minutes after sunrise. Had I photographed this one hour later, the shadow on the face opposite the sun would most likely be black or close to it.
