This sounds like it'll be extremely cool, and you seem to know what you're doing with your maps. I'm excited to see how these turn out.
However, I do want to warn you, don't try to build a ton of stuff in a short period of time. This can be aggravating and really detracts from the experience of map making. Take your time, and have fun with it. I ended up taking several months off from my project, and now I'm back to it, and it's more enjoyable than ever.
Last little tidbit: If you ever want help with anything, feel free to talk to me. I'm a psychotic Pokemon fan, so I'd be more than happy to help.
I'm excited to see how this turns out. From what it sounds like, this should be amazing! We'll see how it goes... Good luck!
Thanks for the advice, I'll be sure to go to you if I need some backup!
