Your tree shadows are all wrong, and the blue house has no windows (and the tileset does provide windows for it, top-right most portion of tileset 0). It's still too right-angly, try to make more interesting curves in your mountains and lake. There's a lot of wasted space over on the bottom left corner under the mountain. Fill it in or put something there. The space between the houses in the middle of the ridge they're sitting on is also a bit too empty. Fill it in with some foliage or something interesting. In my opinion, you're overdoing the flowers, but it's in a way that's at least acceptable, so I'll concede that. Signs in the middle of the road are generally not a good idea. Your stairs are only 1 tile wide. I'd expand it to two tiles. Take a look at some R/S/E maps for some more inspiration and methods to keep your map from looking soo... well, Nintendo-Firered-y.
4/10, but it is an improvement from your last one. Keep at it.

I have a map of my own. It's supposed to be an incredibly small town near the ocean. Admittedly, it is kind of cramped, but I decided to put some of the buildings on the route directly outside the town to give it a unique flavor and because one of the buildings was a large farm (and its land) that I decided didn't belong in the town itself. And there's no mart anywhere near this town, just a Berry Shop on the outskirts. In game, it doesn't seem as cramped because of what's right next to it on the adjacent route.
Name: Fragrant Town
Base: Firered (With some R/S/E tiles imported, and custom tiles by yours truly.)
^I'm certainly happy with it, but I know it's not my best.
Considering changing the house color to a more pinkish color, or maybe a peach? Not sure. I do like the default Viridian green as it is though. Comments?
EDIT: Scratch the pink. Anything that fits with the town that isn't an orange, pink, white, or another type of green. Peach should still be different enough from orange though, right? I'd like some suggestions please. Maybe a blue? To bring the blue from the ocean in and balance out the map?
...This frustration is what I get for taking an art class... :P
