@Sugarpolyp Thank you for the encouragement! I have been sitting on this for so long and suddenly had a burst of ideas tonight. There is plenty of time to revise them! And I have to remember everyone who creates might reconsider their ideas even after the thing gets made.
I'm fluctuating between enthusiastic inspiration, and self-conscious discouragement as I'm writing ideas for a story I've been thinking about for a long time.
