I'm actually really happy and impressed with the result. The layout is fun, modest but not underwhelming or asking for (much) more. I'd like an extra element thrown in, but I say that about many real rides as well--and I honestly think the balance of what is done, when, and the general pace of maneuvers is great. Its very on brand, doesn't push the limit of what Flyers are and doesn't need to be defended or exhaustively explained to those who don't build enough to develop strong, but faithful layouts. Great work!
Theming and environment was simple, but sharp. I like the station detailing! That was pretty great while seemingly was somewhat simple to do. I need to look into doing detailing like that as stations and queues are something I've wanted to start installing and designing into my projects as well.
On a forces and vectors note: I was really happy, and honestly surprised, to see no more than 2.5g on the rider's chest pretty much max (in front car)--as well as those more fun, higher g's being present on the valleys between the big elements. Your roll rates felt perfect, after a quick refresher of watching some quick recently built flyer POVs; and I think you did a better job creating an extremely solid Flyer Package than I recently have :-X
Only thing I didn't like, or more so just didn't personally agree with, was the color of the trains (dumb simple thing that doesn't really matter much). They felt far too loud, and made the train look more awkward than it otherwise would traveling through some of the more advanced roll features, at least to my eyes.
One of the only semi-weakish areas were the terrain textures and terrain sculpting (even if the plot would be mostly flat, having some vertical texturing helps a lot). They could use some better painting and layer textures, too. Everything else is so well done that the more naked and static terrain surface stands out more than it would of otherwise.
