You're doing a great job and it is awesome that you found a community of authors & writers to discuss with!

My main advice is to just keep writing. The finished books you see on a shelf had a first draft that was nowhere near the final product - speaking from experience. ;)

Don't stress too much about getting things right. As long as you have the bones of the story in place, you are good.

First drafts are always messy, a little crazy, and very flawed. But getting to the end lets you see your project in whole - the full course of character arcs, story lines, themes, etc. The things that need fixing, the bumps in the flow, the scenes that need rewritten, will jump out at you on the read-through.
