I wanted to remake a map too.
Thought about Foundation or Sanctuary...

Good Luck I chose Foundation xD
Your map kicks ass^^ looks REALLY great!

At first i thought you'll have problems with the object limit, but you wrote about it so it's fine.
I don't want to happen to someone what happened me

.......
I was completely new to sandbox-forging and didn't know about the object limit.
So I worked on my Foundation map for about 10-12 hours.
Nearly finished some parts were missing and i wanted to finish it...
and THEEEN it happened

Object Limit reached.....F**K
Well i just started new and it should be finished about next week
ANYWAYS
excellent map design =) looks really neat...
