hello I'm new to the world of writing a story and I would like some tips, the story I'm doing involves an Alien arriving on earth and living there, but I'm not very good with descriptions and making characters' personalities work and other details so I wanted to know where i can do research to improve (I had to use translator to help me, sorry for mistakes)
Wikipedia is your go to. Then if something piques your interest, you can do additional research via google, your local library, or from the books available to you.
Additionally, you can also watch documentaries on Youtube.
Edit: Oops, my bad. I got lost in the title.
In any case, you can read a few novels and get some techniques on how tyhe author unravels his/her narrative.
In my case, aside from narration, I also use dialogues to describe the events, places, and characters.
