Need a little help/tips (star wars fiction)

I’m no writer, not really. And I’ve never posted a single short story. But I’m trying to get into it and I’m currently working on some fiction about Rey from Star Wars.

I love details. So I want to describe a lot as a result. I’m asking for some tips and suggestions on how to describe things in detail, especially bodily things, facial expression, clothing, movement, and voice.
