I'm getting a 3D Mario vibe from how this map is turning out.
It has the pallette of Mario 64, but looks like the gameplay of Mario Sunshine.
In any case it looks pretty awesome. It's very interesting the way it's turning out. Something I think would be cool is if once you were done you retextured it, so there'd be two versions. Because it would feel and look like an entirly different map with a different texture set.
Keep it up
