i've written and drawn two manga anthologies (actually, still working on the second one, i'm on act 19, CELEBRATION, it's almost my one-year anniversay with working on it) i've learned that when working on a manga it's best to use your own ideas. this way, you have complete control over your manga and there's the best chance that someone won't take it over or there won't be too many chefs with one pot. one can never make someone else's vision completly how the other person saw it, so it's best to work with your own ideas and make what you see a reality.
