THATS HUGE! Do you have a floor plan for it?
Did you make rooms as you go or did you have a general idea what you wanted?
A frick'n 19 minute video to show it off? Just kidding you.Are the plaques on the walls customized (messages can be edited)? Is that Minecraft standard or addon?
Not that I have much experience with MC, but when I go into a natural landscape, my tendency is to go low profile such as:

I love this Jungle Chateau setting which took about 45 minutes to make. (It's still under construction). Where Minecraft seems to be lacking most (IMO) is when it comes to furniture and other decorations. So for anyplace I build, they are usually just large empty halls with a bed, some trunks, and a rug...Ultimately when they come up with something like MC that is not so blocky, it will be just as big, if not bigger of a hit.
Contrary to blending in, my Rivendell-lite knockoff is more substantial and more work has been done on it.

...Not that I'd ever match the Recreating Middle Earth Project or Planet Minecraft versions of Rivendell!

The server I'm playing is creative until bukkit releases for the new Minecraft so I'm trying to do as much as possible to build up near spawn (and where I'm living) before it goes public. I'll probably build this out into a castle of some kind, but for now it's a sea port. Either way I'll end up "housing" up here for this world. I want to make an ancient greek or mycenaean style city within the walls and add some statues as well, maybe poseidon. Who knows. Towers are still incomplete.

You span has a nice design. I'm very protective of my designs. I don't know how happy I'd be on a public server where collaboration is involved.
