A suggestion: you might consider mounting a few towers on the outside of the walls.
I have thought of that , creating square towers protruding to the outside and therefore creating more angles and top areas for defence , but i wanted to maximise the usage of space and its already taken up and always liked long steck straight walls. I shall be getting soon another order of steck parts in the order of another 1500 parts , I realize i needs twice as much space for building properly the design i have in mind with another set of walls on the outside and teice as big the town space. That wont be happening till late 2011 so meanwhile i have to compromise with this available area ...
When i have more space i will build the outside wall with lots of square towers ( i have over 24 left ) and they shall be protruding from the outside wall giving the design an even more byzantine look , more of an Emperor's Theodosious Wall fortifications of the Constantinoupole. That I am afraid wont be happening now, space is already limited god nows how i will sqeeze on the other table the 5 dragons kingdoms , the forrest, mary men, the magic and the animals and of course the vikings /gauls and their ships !!!! Need more space . and more nuremberg guards !!!
