here are a few things to get you started
1. Make your track in chunks I think people make a layout first, but I prefer to decorate as I go along, it makes the track interact more with it’s surroundings.
2. Make sure there are absolutely no holes and DO add off scene deco.
3. Build props off the track first, then copy and paste them into the track
4. Take inspiration from other tracks and the world around you, this track is kinda a mix of zealot and winterfell
5. I like to make route cross over itself, this make the scenery feel a lot more whole
With Polytrack, practice is key
