Your layout says 22 views, I'm one of them. It's pretty good for a first layout. I know how tedious it can be to lay objects out and make any sort of track. I don't claim to be a drifter, but I enjoy trying. I mostly like the couple of long sweeping turns you have on this one. One downfall, which isn't your fault, is the barriers themselves. If you run into them they send you flying quite funny sometimes
Just so this post wasn't totally useless. you might want to look into using LYTE (Layout editor) It is an external program that makes it a lot easier to create courses. Just search it with the search button to find it.
