Terraforming and painting looks nice. The colors are interesting.
Well, the inversion that is called after my name
, tbh it doesn't look good or has a nice flow.
I would agree with SuperMoose93 and Cheleste here.
Doesn't matter which speed the trains would have, this one would hurt in real.
But the rules say only "no floating things", so unique stuff doesn't mean that it is unrealistic.
So in this case i agree with the others here.
If you like it as it is, let it stay. Otherwise you could change it.
And if somebody has a lot knowledge about real layouts and coaster forces/mechanics, than it's Cheleste.
So if you wan't to build realistic as possible, ask her.
But in the end, toofpikk will be the importent person, he is the judge!
If he likes your design you will win, doesn't matter if real or semi-real or unique.
I would also recommend to integrate a pretzel-loop somewhere, because this kind of inversion is what makes a flying coaster.
Other than that it looks really nice so far.
Soo long, Cobra
