Just a heads up, timeline parks require a lot of effort and time to pull off properly. If you're outright acknowledging you don't want to put that effort in, it's probably not something you should be pursuing.
Not trying to be rude; I like seeing new parks and what new creators are capable of, and when they're done right, they can be really damn good. Outright stating you're going to half-@ss it gives me absolutely no assurance this will turn out at all. Given the sprawling paths with nothing on them, bleak lanscaping (seriously, why is the pond black?!), and the unbanked turns on all of your coasters, I'm sorry to say the lack of effort really shows in what you've shared.
I'm sorry for all of that. I will try to improve everything I flopped on, but it may take a while.
I am thinking that I shouldn't do this. I am losing confidence, because my laziness always dominates me.
