I would say it is impossible to predict the future. But anyway, I'm thinking of trying to make a cartoon on my own, mostly technical. As limited as it is.
And then, the problems pointed out by some are a real danger. Because I don't know about you, but in my country setting up a business to become a freelance writer / artist is no fun at all. And the post-creation is even worse.
And to finish it all, (which I will say just reflects my opinion) you have to be popular enough to be able to convince large production companies (mainly in the West) or production committees (only Japan, no idea of the system / mode of other Asian countries) to put their money in our series.
