For your first track, it is a good attempt. You understand pacing, and there were some nice pops of airtime. All the issues with the ride are easily fixable, and the techniques to fix them will become 2nd nature as you build more rides.
Technique: I rated this a 4 because it is your first ride. The track, for a first attempt, was quite smooth. The issues here are more about the basics - making the lift hill and brake runs perfectly straight, ironing out transitions, etc. All of this will improve as you build more. The final set of bunny hops weren't paced or shaped the best, but again, you'll get better at this over time.
Adrenaline: I rated this a 5 because, again for your first ride, it had some nice moments - especially with the airtime.
Originality: I only rated this a 1 because an out & back wooden coaster is... well... boring. They've been done to death. It's your first ride, so this layout likely made the most sense to you. Don't be afraid to branch out and try different layouts and ride types. It's all about trial & error (and looking at every tutorial possible).
Overall, this was a nice 1st attempt. Familiarize yourself with NL2 editor mode and the tools there, and you'll start to get the hang of it. If you want to stick with basic layouts, I suggest making another wooden coaster - this time with an 'L' shaped layout - just to get used to some of the other tools.
