Any writing tips?

I would recommend to picture the scene you’re writing in your head and describe what’s important to the scene. For example if the characters are in a cafe picture a cafe and the most important things, describe the chairs, the decor, if there’s other people in the cafe make note of it even if it’s just “a girl is sitting alone in the corner her face so close to her laptop she could get sucked into it”. It makes it easier for the reader to picture the scene and it’s good to have a description of the background of the scene. When describing characters make it so you have enough understanding of the character that if you were to later point out something about the character that they’re recognisable from that ,ex. make a point to describe their eyes, their hair, a unique fashion choice such as a hair clip or a ribbon. This way of character A sees character B out in the street you don’t have to write “character A saw character B waiting at the bus stop in the rain” but you could write “character A noticed a light grey sweater out of the corner of his eye “CHARACTER B! HEY WHAT ARE YOU DOING OUT IN THE RAIN!””

I’m not sure if that’ll be much help but if you ever need a proof reader i’d be more than happy to help you out, just shoot a message and let me know and i’ll give you my discord !!

It's great that you're letting your first draft flow freely! When it comes to "showing" instead of "telling," try focusing on the characters' actions and surroundings to express emotions. For instance, instead of saying "he was angry," describe how he slammed the door or his face turned red. To help with not being overly descriptive, you could use an article rewriter tool. It can help you find different ways to express the same idea concisely, keeping your story moving without losing depth.
