I think with the house at the bottom he was going for a side door house. Well actually I know he was, yet that is a really bad idea. I've played through a bit and have come to see that your NPCs are a little bland. They all say the same things, and most of the time there is no point in talking to them. (And remember, this is all just criticism, so don't think I'm angry or anything ;) ) You're shops interior needs to be in the sam- no, all your buildings' interiors need be relatively the same size (and a little less important, shape) as your exteriors. It clashes way too much. Here is an example shop based off of your map.

Try to change your map with my map in mind. You don't have to make what I made, but I am showing you some basic concepts. I know, the screen-tone and blur didn't turn out well...
A few more things you should change are:
The things you can find in the various pots and shelves. Use an AMS to put both of those text strings together with a Wait - .25 - seconds command or two so we don't have to go through two texts.
The large empty spaces everywhere.
Bland and semi-pointless maps. I.e a forest map or two.
Improper grammar, spelling, and dialogue.
I'll give you a few more pointers when I finish the demo today or tomorrow.
