Calm down, Fixet. Last line of my post was "hey, there's no point in being that harsh", not "if you don't like it, go to hell".
I use to take every opinion into consideration. Obviously, there are some points that don't affect my work at all, usually related to game dynamics and such (go with those to dev team, I'm just the guy who draws the map). And I will tell the same tale again: the damm thing is not finished yet (usually, a dev's catchphrase

, badumching!). There's still much to be done, I'm testing stuff as I slowly structure the drawing, test colours and textures, sketch the wards and add "map furnishings".
On the "map furnishings" issue, there's a bunch of them: city banner, motto and coat of arms are used almost always on city plans. Besides, there's the compass, the sea serpent, the "here be dragons", the wind blowing cloud / greek god and such. I'm beginning with the basics... but I'm open to good ideas.
You said you like it "sketch style". Know what? me too:


The coat of arms, city banner and motto is something I would like to include. This does not mean that they have to be the first ones I drawed. So, if you people have any good ideas on this subject, now it's the right time: Coat of Arms and City motto (the name stays the same, I guess...)
The coat of arms at this moment is not the best, I ran out of ideas. On the other hand, I think the city motto is a good one: "Quod magia non dat, vis non praestat" -Which (whatever) magic doesn't give (achieve), violence (might, strenght) doesn't lend (gives instead of, substitutes).
And, Shinteo, different colour is possible but I was trying to make them "look" different using various block shapes and street structure for each ward so it worked even in monochrome.
