Whenever you are stuck telling a story, it's always good to take a few steps back. Good, but easier said than done. You're STUCK, remember !
A fresh perspective can make a ton of difference.
I have performed story surgery on many feature projects: analyzing scripts, figuring out why they won't tick. I've restructured story lines and -on occasion- done partial re-writes.
Over the years I coached a number of talented young filmmakers on their first animated projects.
Reach out you want to get unstuck. Or if you just want a solid second opinion.
