Yes mearrin69, the upper one is an artificial trench and there will be fortifications too...
I'm doing some try at pseudo-3D with the fortifications, but it's too time consuming and sincerely while the walls and towers are not too bad (towers are still without shadows) I cannot find a way to make houses etc without actually draw them one by one, shadows and all.
The temple is made in a way more simpler style... Any suggestion is welcomed!
