my first coasters

I recently started designing coasters with this program because planet coaster isnt good enough. Here are my first 4 coasters I made.

1. coaster: beige/black intamin rocket coaster
2. coaster: blue/blue Gerstlauer infinity
3. coaster: grey/red Schwarzkopf shuttle coaster
4. coaster: orange/red Mack Megacoaster
