The only thing that I would add to Chashio's comments is that A hand drawn CITY map is a long process if you want a large population and individual buildings (all those houses have to be put in individually, and even copying/rotating takes time). You might want to think along the lines of just showing blocks that define the streets instead. Esp. if it is a modern city. The rest of the elements in your sample work equally well in a modern city map. How much detail you want to go into all depends on what you are going to use it for after writing the story...if it hits File 13 after the contest, I wouldn't spend too much time sweating the small details.

I THINK that we have somewhere around here a guide for how many building per size of populaton in a certain density sort of thing....Not too sure where, but first thought is in the Reference forum....
