I like the hexagonal layout of this city, Jester: it's more unusual and interesting. It suggests a mostly planned city, though, in which case you might expect to see a more planned city layout (eg, see Palmanova, Italy).

I recently gave someone some tips on their city map layout in this thread, and you might find some of those tips useful. If you want me to give some advice about the layout of your city directly, let me know - it might take me a few days to a week, but I could probably write up something for you.

It would also be easier to understand what's on your map if you add some labels to show neighbourhoods/landmarks.
