Not really. Roofs should be longer than walls are high.
I think it it usually looks better to have roofs two tiles high, but change to fit the shape of the house, of course, if going with small windows :3 Anyway, good screenshots guys. Now for some evil >;3
Liberty - First, I think the road needs to be more interesting, with so much empty space on the road, I think it needs a little more detail to stop it from looking plain and empty. On the left, inbetween the red roof and green roof houses, there's like a floor of gray there, I'm not sure what this is but to me it looks a little out of place, I'd consider changing that for grass. Now, for the stone roads going to the houses, I'd consider replacing the borderless path for the bordered path you use for the rest of the road, then you could also shift the grass under it. I'd also make the bottom wall a tile higher and the wall's roof a tile shorter. Finally, I think the roofs of houses need to be a little smaller and the houses to have a few more windows on them, maybe :3
Sorry for the block of text ;3
Voci - Are you familiar with shifting? I think your grass in the town needs some of this where the grass meets the house. I also think there should be a little more grass in the town. I'd also shift the fence, where there is the little farm, so it looks like it goes behind the house with the red roof. The two angel statues, I'd move them infront of the church rather than near the graveyard, and I would place another kind of statue in the middle of the graves, with a dirt path going between each grave, rather than having them bunch up. I'd also put a fence around the graveyard that joins to the back of the church, although I'd put all the graves infront of the church, as that's how it is here in england and that's how I end up mapping them x3 There are quite a few more things I'd like to see you change, but I can't figure out the way to word them at the minute, so I'll have a think about that then post again ;3
Again another block of text, very sorry x3
Necromus - Alright, I have two main problems with your map. Number 1! I think the house walls are a tile too high. Make them another tile high for a second story or take a tile off just for one story. Number 2! The houses look so similar! Change the shapes of houses, change the walls and roofs so they look a little different from each other! Number 3! (Wait wasn't there only 2?) Put more breaks in the forest! And add grass in the forest breaks with flowers and butterflies and other pretty things :3
This one wasn't so big, sorry (not really) (>w<)b Anyway, good maps guys, I hope my advice helps a little bit :3
Edit - Wow I wrote so much XD
