The assignment was to produce three different renders of one model. In the upper left photo you can see the structure of the 3D subway car I modelled. Next I changed the advertising and adjusted the texturing on each copy of the car so that it would not be blatantly obvious that I'd only modelled one car for my subway train. The upper right photo is the beauty shot of the subway train but it looks too pristine to actually be in service.
The car on the left below is the stereotypically suspenseful low angle view from on the track as the train bears down on you. In contrast I envisioned the train on the lower right to be bathed in the blue moonlight as the empty train heads back to the barn in the middle of the night.
