None of this is meant to put you off,
@rservello. Writing is
hard, and the publishing business is merciless - but for many of us, writing that first draft is by far the hardest part. Many people never get to the end point of that, so you're ahead of the game. You just want to give yourself every shot at success, which means knowing a lot more about how it all works.
But you're on the way and you've found yourself in a good place to pick up some excellent pointers.
Good luck with the next step. For me, that would be putting this draft aside for a couple of weeks, and then (since I think you started it three months ago?) coming back with a clearer eye. I wouldn't be getting readers involved just yet - save them for the complete, polished, proofed stage because a good reader is a terrible thing to waste. In the meantime, you could do a lot of reads and crits in SYW. It's not mandatory, but critting other people's work is a great way to learn.
Good luck with it. Writing is hard, but it's such a privilege.
