For the lighting in the scene I am using a variation of the
I deviated a bit from the theory and added a fourth light, underneath the sun. As you will notice none of the lights cast shadows, except for the sun which only casts a shadow and no light at all. This is because the sun casts a very strong shadow on the ground plane, which is necessary to be able to have a black ground shadow. The other front light is there to provide the front side of the building with sufficient brightness and to soften the shadows cast by the sun on the building itself.
See you there,
