Hey Pikkio, I understand your frustration right now - getting the final details right on a map can be a drag, but when it's perfect you will hapy with the final product.
I see now that the "Courts" are the land around the walls. My trouble is that the walls are "impassable" - so how can the courts attack them? What I really think you're trying to say is that the four straight wall stretches are impassable, but the Towers (which in my mind are a part of the city walls) are not. This is not clear from the map.
One possible solution: introduce a siege tower on the territories that you want to have attack the Walls, and not in the legend that Wall Towers attack Siege Towers and vice-versa. Or explicitly state somehow that towers are the routes in and out of the castle.
As for the catapults...

I haven't played Civ recently enough to remember what the catapults look like, but whether or not you are using a free version of Civ is not the issue. Images lifted from another game are somebody else's work and are subject to copywrite. Likewise, if some free CC user took this map and posted it on another website as their own work, they would be guilty of stealing your work. If, indeed, you have significantly changed the catapults and made them your own they're probably alright. Since I haven't read back through the thread, where do the other images come from - windmills, houses, trees, etc?
Borders: the colors of the borders in the desert and in the mountains are simply difficult for me to make out... for instance, I can't tellif that lone tree below the flats is part of Quicksand or dead space. A bit more contrast with the surrounding color would help me out.
