Thanks Valouchufy! The light rays are a very light pale yellow gradient (I'm thinking of re-doing it since I think I want the rays to go to the ground).
With the Polygon Lasso I drew the general path i wanted them to go, made the gradient, then masked them so they had soft edges. There are 3 layers of them - 1 for each window - and the layers ar in Screen Mode at 70 percent opacity. I then masked off a drawing of a person's silhouette and shadow in the light.

There are several Levels Adjustment Layers to dodge and burn in color, shadows and highlights.
Take care-
