mix with sketch up and photoshop

I used sketch up to make my shed. I made cubes and spheres to create the lights and city buildings. I am using the lights as i want the buildings to reflect onto the walls that is covered in the world map. The floor is covered in grass and is going to have animal manure on it to represent my farm but without having to put animals in. it will also give the idea of a unusual smell of a farm when you are seeing city buildings which is not a common thing
