One more suggestion for the tower, and then I'll get off your case
:
It looks like the back of the tower is tapered all the way to the top. If you make part of the back wall straight vertical (so that part of the tower is a perfectly rectangular box), that would make it much easier to alter its size to fit whatever castle walls the attacker is facing. I notice a lot of request for variable height walls in the thread. You could even add an optional midsection for the tower to change the height as needed, or provide this as a freebie or upgrade kit later.
This is something that could be easily kitbashed by the user, but for the same reason it shouldn't be too much work for you either, and it would be a very useful feature for a siege tower.
