Kyriakos, the city looks great!
Suggestions:
Please avoid this time the big mistake you nearly always make when creating ancient or medievial cities (and you mostly create cities from those eras).
Especially size 2 and size 3 cities of era1 and 2 had city walls! It is wrong to show only size 1 cities with and without citywalls. In Civ 3 there is only one slot for citygraphics for size 2 and one slot for size 3 cities - but these graphics in era 1 and 2 should show the city with city walls! There was no need to provide size2/3-cities with an additional graphics-slot for citywalls, as these cities in the settings of Civ 3 always have citywalls.
It is a missunderstanding between Civ 3 game-mechanics and the graphics of bigger cities of era 1 and 2 in civ 3. In terms of gamemechanics cities with size two and three have automatically citywalls or massive citywalls.
In the general settings of the editor the defense values are as following:
1. Size 1 city (Town): Defensive Bonus 0 - can be risen by building citywalls to 50
2. Size 2 city (City): Defensive Bonus 50 => this city has a citywall (Era1 and 2)!
3. Size 3 city (Metropolis): Defensive Bonus 100 => This city in era 1 and 2 has a massive citywall !
From the setting of gamemechanism and mostly history it is wrong to show size 2/3- cities in era 1 and 2 without citywalls.
