Awesome. I'm in a similar boat as far as writing. I'm working on a story as well (one with a lot of fantasy elements too!), a bigger story than I've ever attempted before, and I'm allowing myself a lot of time and effort to make it the best it can be.
I dig the positivity and general intention of this post. And I'll follow to hopefully be able to read your story when you finish it!
