Nwbi has good ideas for the temple thing. I was kind of going for that too, as "temple", literally, is a bit bland and not-Touhou and not-CPMC.
I can attempt to texture things, maybe possibly idk. I can't say how nice things would turn out (as I've never done things of the sort before), and doing even part of the soundtrack and other various things is quite a bit. Although, I am good with Photoshop, I am good at dealing with how pictures turn into a scene and I do know how possible it can be to map certain images in a 3D plane and can make graphics accordingly. But I still don't know.
