Map of "city" in one day

If my memory serves me correctly, I believe I needed to do this city map in one day. The general purpose was to illustrate several different concepts as places, like....The InternShip, the Tax Tower and other like minded puns. I had to incorporate a river, bridges and roads going through the entire illustration but, keeping in mind, the buildings would all have to be separate icons. I had to draw everything in layers once I plotted out the imaginary town, not to mention, scramble for reference to see what the buildings would even look like. I chose a generic perspective and a generic style as i didn't have too much time to think of much else. I believe I even drew more than this that day in only nine short hours.
