Excellent Series... JKD in flash....
....I really appreciate what u have tried to accomplish in the series, - being a self taught pupil of JKD. The reason I chose JKD is because of the philosopy & scientific nature of it, yet it has spirit & flow. I feel you tried to capture that in nagashima & Jyhasa. maybe you should make one of the episodes a fight scene with a little more detail.. you've got the skills... to do an excellent grafics focused fight scene... just a bit more effort ( Which i - myself lack).
Have you thought about building in some of bruce lee's concepts of buddhist philosphy in JKD...? Maybe nagashima could .... attain martial arts enlightenment.... be the water that fills the container.
Anyway Im sure whatever you do with the series it will be excellent - I just cant wait!!
