This is really nice, a convincingly Roman feel. The roofs look great, and I can only imagine the amount of work involved. The subtle canvas texture is an especially nice touch, an emergent effect of the cobbles and roof-tiles.

I like the districts, and especially the inset map showing their outlines. But color-coding the roofs by district on the main map seems a little out of place with the more natural, almost photorealistic palette of the farm plots and surrounding woodlands. Stylistic preference, is all.

How did you decide on the placement of individual guilds, villas, palaces, etc.? I'd be very interested to know how you developed the layout, which clearly has a lot of thought involved.

Also, on your key to locations, please note #4, "City COuncil," and #27, "Gunder CHief's Villa."
