Siege!

Okay, here's the deal.

I wanted to make an adventure map based around a large castle/fortress being sieged by the forces of the night (i.e. mobs). The hiccup I've run into is that I've never been very good at large, complex builds in Minecraft. Once the fortress is built, I'll be able to handle the technical details myself, but until that point, I'm going to need some help.

That's where this post comes in. The world save is linked below. Feel free to download it, have a look at it, and make some changes if you'd like. I've built a few towers and gatehouses, but I'm having difficulties with the interior. Any and all designs and suggestions will be considered, so long as they follow the general color scheme I've started with. I've also placed a few signs in undeveloped spots with an idea of what I want to be built there, but those are more guidelines than requirements.

Cheats are disabled, but the default gamemode is creative, so that shouldn't be a problem. Also, you should spawn in the castle area, but if you don't, open a LAN game with cheats enabled and teleport yourself to (-209,96,375).

Thanks in advance, everybody!
