First Stage: Storyboard and construct the entire fight sequence as specific as possible. This could be done in the video below, map chart, or simple doodles, as long as you have a clear understanding on how the fight will go about.
Second stage: Select the key moments in the fight that are most important to shorten the sequence yet still convey the same information as the previous stage.
Stage Three: Arrange those key moments of the storyboards and arrange them in select comic book panels. Certain sized panels show importance and even durance of the sequence. Also arrange and size them to have the reader's eye flow thorugh the page smoothly.
