I hold dear to British artist Jamie Hewlett's (Tank Girl, Gorillaz) credo:
Start an art in a spontaneous way, with no planning whatsoever, no storyboard, just draw as your hand leads you. Randomness is your muse.
sort of what my martial art instructor told me before going to the fight...don't think, don't anticipate, but just go with the flow....
I just load up Posette. And i randomly pick a freestuff (prop, building etc) and from there I construct a story, an art, a series....
...just like and indie movie. So unpredictable.
