I’m not a professional though so all things I’ll write is my personal opinion. I think first of all you should accept the fact that you won’t be able to write a great script in a day. And even when you finish the script you should put it away for a while so after some time you can revise it with more clear head.
Ah, thank you, Nonie! Right now I’m drawing illustrations for collaborative artbook with other artists (FeelSeeDo - art-group). I’m thinking about making my own A5 artbook. But I’m really skeptical about it… I’m not sure a lot of people would buy it so there’s a high chance I won’t be able to sell all copies.
(even if decide to make an artbook it would be next year :3)
