thanks for the update!
I think it'd be interesting to either have a 'forward' or 'authors note' kindof deal...with perhaps a short blurb of how your artwork and martial art converged to make the book. also perhaps mention a short ditty about the real bubishi. and then make sure you give your thanks to "some guy named Ed". lol j/k
[add]oh, and make sure you reference Pat McCarthy's HAOV work if you mention that source. "Habitual Acts of Violence" is practically (but arguably) a copywritten phrase.
