I need inspiration for a hanging monorail.

I have been trying to design a futuristic hanging monorail, but I have no idea how to. I try to look for inspiration, but most are very boxy. I want to make something like this https://www.artstation.com/artwork/m89zKa but I just cannot achieve it. I am using the framed blocks mod btw. But if this is possible without that mod, I would much prefer it. Let me know some suggestions, or some pictures that are in minecraft for inspiration. Thanks.
