Firstly, everyone has to start somewhere, so the effort is nice. After that I'm afraid to say this is a very basic track which doesn't look a lot like the real thing; one of the many issues of use RaceTrack Builder instead of modelling from scratch. The file structure is broken, no model.ini so the track won't even load.
Its great to see people trying to build tracks but you really have to put some time in to learn the basics. Learn Blender for modelling; it's free and there is loads of help out there. Learn the basic folder structure for a track. Learn how to create AI, outline maps, track maps etc.
Keep trying and I'm sure we'll see improvements over time!
