work on the presentation. rehearse it so that you dont have to try to remember your patter.
I think this would be better as a ghost story without magic, Darwin Ortiz spoke about the weighing of story vs magic in your presentation, and I think the story outweighed the magic
but still very entertaining... at least at the end.
Yeah I am kind of sitting on this now just letting it stew for a little while in my mind and possibly doing some performance tweaking the patter a bit. But my process is a slow one at times.
