I'll be honest, this feels like a first draft stream of consciousness piece. Sure, some of my favorite grimdark fictions are based on the casual moments in a wild setting, but feels like a single (drawn out) scene in a scooby doo play. The character's races are very artificial and have no bearing on who they are/what they want. The most climactic moment is a character using a piece of tuba to physically hit a ghost in the shin- which only creates more questions. My main advice though is to make sure your characters have motivation- our heroes have "nothing better to do" than to wander around the bandhall and we have no idea what the Elf Spirit was after except maybe it was a little frisky for some reason (The roles are reversed haha). With that in mind, you clearly have the capacity to be a great writer, and I'm eager to see what you bring to the next jam!
