Hi shrimpsdad.
If you have already finished this you should give yourself a large pat on the back for actually having the grit and determination to actually finish what you started. That is quite an achievement in itself. You are now finding, as most of us do, that writing is a craft that has to be learned. A lot of the craft is probably already in there somewhere but just all messed up because the natural and perfectly understandable enthusiasm and desire to get our first story written has taken priority over learning/discovering techniques.
Sadly, for most of us, folk won't automatically read what we have written simply because we've written it.
Anyone can lob out 90,000 words or whatever. Only by practice and learning can we make sure that what we have written flows smoothly and with clarity from one sentence to the next. Proven techniques help us write in such a way that when folk have read our first sentence, they want to read our second sentence, then the third, and the fourth and so on for hundreds of pages.
You are already pretty close to the 50 post mark, which will enable you to post ,say, the opening 1500/2000 words of your novel in the appropriate Share-Your-Work Forum.
It's a lot easier for critters to pin down areas you might be able to improve upon, when they can see actual pages of your own writing.
Story structure is a completely different kettle of fish, but no matter how the story is structured the basic elements of the craft of narrating it to the reader remain the same.
That's one huge tale you have and although I've read about it a couple of times in more than one thread, I'm not sure I really follow who's story it is.
Anyway, look forward to having a peek at your actual writing in due course.
So far, you get full marks for enthusiasm and imagination.
There's plenty of How To ... books out there, but I hesitate to recommend any at this point.
You're treading a well worn path and I wish you well on your journey.
