Fantasy Writers Club Forum New to the site

Hi everyone, I'm new here as well as relatively new to writing. It's a bit of an ask but I currently have three stories up on my website (www.storiesofatlas.com) as well as here. I've finished the fourth but not published it anywhere and I'm currently working on my fifth.
The latest one I'm trying to double the length and I'm worried about ruining the pace as I have a lot of detail to explore as well. Pace is something I'm always worried about whilst I'm writing and I think I rush to get to something interesting sometimes, if anyone has any tips I'd be greatful. Also review me :).
