I have greatly enjoyed your two previous tiles and found them very useful (I unabashedly say that I "steal" stuff from here all the time, but only for personal use, and I never claim to have created it myself). I look forward to seeing the city fill out. If I may be so bold, a tavern is something that every town needs (and which you seem to have overlooked). Other ideas may include a "punishment" square (perhaps with stocks and a gibbet) and/or a shrine or temple.
