Remember that when light hits the subject ‘Head-on’, more often than not, the lighting is flat and uninteresting. You may want to place the subject so the light falls on it from one side. This may cause shadows on the opposite side you may want to deal with. However, lighting a subject from different angles and the consequent shadows are more interesting than flat head-on lighting.
You will do well to experiment with light from different angles! Happy Shooting!
