Sometimes, when a scene isn’t working for me, I like to imagine I’m seeing it from a plane or spaceship hovering or flying above it.
I look at the aerial view.
Are all the participants in the right spot? Have I forgotten about a participant? Who is in the most danger. Am I telling it from the right character’s perspective?
Looking at the scene this way gives me a fresh view of it. It takes me out of my current stuck mindset.
And often this helps!
