Coaster

The track is profiled pretty much perfect: It's smooth and exactly Mack-like. The support structures are also just as crazy but realistic as on the original Helix, though there are few ones that look a little bit too wacky. Other than that the layout interacts really nicely with the terrain and the queue.

Scenery/Theming

Hands down with the station building, I always love to see people making custom modeled structures around their coaster. Huge plus point, the default station really wouldn't have fit the style of Helix. It's slick and modern although a bit too grey in my opinion. Yet again the green lighting adds a really nice tone to the coaster. As for the terrain, it's not at all arbitrary which is often the case with NL2 parks, you chose a nice hillside slope coming down to a river.

All in all, an extremely well-done coaster and you definitely hit the style of Helix, both coaster- and theming-wise.
