1. Add streets. Put no houses in the streets but on the blocks. 2. Have a horizon (blue). Draw distant houses first. Houses in front occlude houses behind (a 3D visual cue). 3. Draw the town using the on the street view but 5-6 feet tall view (as we do in class). 4. Even add a street lamp (use functions) or a tree where tree = ((triangle-fills & rectangle) for evergreen or (circlefills & rectangle) for deciduous).
