This is pretty damn good for a first track. At the very least, I like it a bunch. It's not terribly difficult, but that gives you the option of styling all over.

It's pretty clear you learned a lot while making it. That's great, but it seems you forgot to go back and revisit some of the stuff you made at the beginning. The worst offender is probably the 90 degree wall transition just before the big jump through lasers.

I'm gonna make a discussion topic with a few more suggestions, if only because I think this could be a really great track with a little tweaking.
