Dungeon Hall

Well, I am making a Server soon, but I am actually going to put some effort in to building stuff..
So, it will have many parts, one of them, a large underground hall, the pictures above should give you the idea, yet this is only the main hall, I will expand on this and add things like dungeons, catacombs, maybe sewers, I would appreciate any ideas and your opinion on it, constructive crit please, not just outright flame. This will be the spawn.

INFO:

More info on the server, release date, what it's about, etc?
I'm not to sure yet, I have a few Ideas but I'm coming up with most of the stuff as I go along.

Download?
This will not be up for Download.

Texture Pack?
In these screenshots I use Rome-craft, this may be a Roman themed server, i'm not sure yet.

Can I help you with the Server?
Depends, if you're interested, message me!
One thing I would like is a texture pack, but I doubt anyone would go through the effort of making a pack based on my requirements apart from myself...

Do you have Admins?
I do have a couple but there are spots open yet.

Any other questions?
Any other questions that you have to ask that I think will benefit others, I'll put them here!
