Hey welcome to Roleplayers Guild!

As far as advice goes, I'd say just relax. Honestly you don't need to worry what anyone else thinks about your writing. We are all here to enjoy telling and sharing stories and characters. 

Just write it and let it be. Don't worry about whether it's good enough or if people like it. Otherwise you'll be stuck in a loop. 

I'm part of a group that does "Isekai" rp or magically transported to another world. We are always open to new folks and non judgemental. 

If youre ever interested shoot me a message. 

Hope you find what you're looking for! Happy roleplaying
