Some lighting and perspectives allow for quite realistic looks. However, this screenshot was altered. I used the same trick like Fallout motive. The image was resampled to a very low pixel size and resized. This allows for a dirty and rough look. A also desaturated the picture due to heavy coloring at the curbs in the foreground that made the picture unrealistic. I think the result is pretty good on this one.
