Shagari La [Ideas would be appreciated! ]

Just a rather large build I have been working on for what feels like eons. Got to thank Pwego for the awesome ideas from his YouTube videos. And yes, fans of Pwego, those are his towers. I watched the video of it hundreds of times, and was apply to replicate it. But the rest is of my design, influenced by Pwego.

Concering Written Permission: I have attempted to contact Pwego via YouTube, email, forums, and PMC, but have yet to get a reply regarding this project. I will assume he is not against this project to the point of wishing me to remove it. I welcome and encourage anyone to attempt to get a reply from Pwego on the matter, as I do not want to upset him with this build.

I will be uploading a video of this soon, and possiable a show off of my house (since my house is hiding away in this build!). I may also be uploading a map of this when it's complete, but that's all in the air still,

If anyone cares to see it on the livemap, you can visit the livemap on my server, and go to the co-ords 13,64,477.

Additional Notes

The outline is in place, but the inside is no where near done. Just thought I'd share this and see if anyone had any ideas to share for it! So far, my plans are as such:

-Tower bridges will be made into guard barracks, seven in total (one of the towers is actually sealed for my house)

-The four towers will be made into homes. Each floor will hold two "apartments" and each tower has about 6 floors.

-The underwater area will be made into a garden and travel hub. There are four rails going to smaller hubs under each tower bridge, and will go to other places. There is also a glowstone block in the centre of the entire place that is actually a gate back to spawn.

-The main centre structure is where I need help. I plan to make a library, a PVP arena, a crafting/blacksmith like area, and a lounge. But all of that would only take up about 30% of the middle build.

-There are six levels in the main structure. Within that are twelve decks (that's what I've been calling them), one solid floor with a circle missing in the middle (refer to pictures) and the "attic". The attic could be expanded to be made into two levels, but with the space, it may be perfect for that PVP arena.

Ideas and critics are welcome on this one!
