Noticing Newbies

Hey there,
I'm completely new to writing and have no clue what all the tips and tricks are.
But for a few years now I have been watching a lot of fantasy tv shows and anime which gave me ideas like "what if this story got mixed with that story".
So now I have a bunch of ideas, no clue how to write them, and no confidence it will be any good at all.

Thats why I am here.
Just going to write what I'm thinking off, get feedback and see how far it goes :)

Cheers and maybe on to something good in the future
