At present, I've got it to the point it's an even bigger "monster" than my Tudor Castle Rethink (134.3MB compressed!)
See my previous answer. 
If anybody wishes to take a look at this behemoth of a project, you're welcome to do so and I've added a link to the file below. If anybody has any suggestions on any other improvements/modifications, I'd be happy to hear it. 
Perhaps Something like this for the upper terrace...
