Thank you very much for all your comments! Since my Lego city is in Sicily but I'm actually in England, I can work on it only in summer and on Xmas for few days. This is a first attempt to build a city! So I will expand it for sure but first I wanna buy bricks to complete buildings like stations, and church. I also don't like the blue building (that is meant to be a bank).
@Brickviller: your city is really amazing! I will comment soon and take some ispirations :D
