@silent darkness: I think, it still looks waaaay too big and empty. Unless you have a market place, a square in front of a royal building, big crowd of npcs at one place of your city etc., you only need about 4 tiles walkway. Bring everything closer together, it does wonders for the overall look. If you are unsure about it, just copy your map and try it out with every house maximum 4 or 5 tiles apart. And I would place more decoration like barrels, crates. Also, some house walls look really small? A good guideline is having walls 2 or 3 tiles high for the standard sprites.
@phoenix_rossy: Looks good so far, I like how you used the floor textures. I would place a shadow under the gallery and the right staircase. And maybe use taller, 3 tiles or even 4 tiles high, windows?(pandamaru has some lovely church windows, I made normal taller ones, too. Just a suggestion ^^ )? What I don't quite understand is the part with the bookshelves. Can you even access them? I would maybe put 1 tile space between the upper and the two bottom ones. They need shadows on the right side, too. Maybe that's why it looks a bit weird. And on the right side of the room you have one of my book console (desk? don't know the english word). I would put it up against the gallery pillars and put a book on it for instance.
