COULD ANYONE THROW ME A FEW CITY MAPPING POINTERS?

If your map is too big, I'd recommend taking one shot of the map in 1/4 or 1/8 zoom (not in the event page: squares and grids make it hard to see), PLUS one ingame screen of a representativa section of the map.

If you want it to seem more like a city, put the buildings side-by-side without any space in between. Cities are denser than countryside villages.

Not every building has to be enterable, but don't waste space. One method is to make buildings that you can't even get to the front of. Just don't give them doors, or the player might spend all day trying to find a way to get there!

You can make roads, rows of buildings, and anything else run off the edge of the map. This gives the impression that the town continues well beyond what the player can access. If your style of mapmaking includes the general rule "walking to the edge of a map takes you to the next area", then you'll have to get a little bit creative with how you do this.

Multiple heights can help - a brick wall that leads up or down from the main level, and on the other height are buildings you can only see parts of. The fact that they're a different height can work as a visual clue to the player that they're not part of the accessible town. Making them be darkened or washed-out colors can help too.

Also, it's not a bad idea to have a "central" idea for your maps.... try planning them on paper first and you'll end up with something that doesn't feel like you just tossed a bunch of buildings together.

LockeZ knocked the nail on the head.
To add to it though, you need not make this city all in one map - you can have several different ones for different sections. Not only can you then spend time detailing and livening up each section, you can still have that sense of openness and grandeur; with inaccessible buildings acting to tell the player that the city goes on beyond what he or she can explore, and multiple maps making it seem large without actually being so.

I loke those screens, they're not bad at all. I like how you designed the layout of the city. The only problem I see is too much empty space. Roads too wide, too much grass, etc.

It looks like a suburb, not a city. Get rid of the grass, replace it with cement. Or with buildings.

Here are two reasonably dense cities from FF6: Nikeah and Zozo. Nikeah has a sizable outdoor marketplace, while Zozo is a slum. You can get a lot of good ideas from both. Note the heavy use of cement and brick ground. Roads are all only two to four tiles wide in Nikeah, though Zozo has a couple of slightly larger areas because it's full of random battles. Both have plenty of buildings you can't get to - in Zozo they all run off the bottom edge of the map, while in Nikeah they just don't have doors.

If you want it to be really urban, here are some blurry maps of Koorong from SaGa Frontier. Note that only the upper left quarter of that image is the town proper. The three screenshots with neon signs are outdoors, while the others in that section are the insides of buildings. The rest of that image is the abandoned slums and sewers that serve as a dungeon. If you want your town to look less modern, just get rid of the neon signs. Once again, about half of the buildings aren't actually enterable. Though in this case I'm not sure why, since there are as many outdoor vendors as unenterable buildings... Maybe street peddlers felt more slummy to the designers?

The biggest problem I have with it is that the houses have NO depth. make them look a little bit deeper, have 3-4 tiles of the roof stacked on top of each other to make it look like it's more than just a wall
