A good story is an edited one. The same rule applies to fight scenes. A sloppy fight scene can slow the pace of your story and/or confuse the reader.
When editing your fight scene, keep the following in mind:
Don't include a blow-by-blow of what happens in the fight. After your initial draft, remove non-essential details that can slow down reading.
Delete flowery language. Extra words drag the pace. Remove every single word that you can.
Consolidate characters to reduce reader confusion and frustration.
