In general, when lighting a scene, I find Distant Lights more efficient and work better than spotlights.  Another tip.....Play with your shadow softness and bias.  In nature, rarely is your shadow hard on the edge.  Never is your shadow the same from one light to another...for instance, right now, there's a light on in my living room, uncovered lightbulb, and there's a light on in the stairwell, covered lightbulb.  The shadows in my living room are harsh and ugly.  The shadows in the stairwell are soft and subdued.
