For two days I've managed (kind of) to block out any thoughts about my paintings and my work in the studio - and concentrated on the children's book. I imagined I entered another mental room, which helped.
It turned out to be hard writing the script without knowing what my characters looked like. Or, rather; I wrote a script according to our instructions for the exercise, but even though I thought the story was good - I didn't at all feel like illustrating it. It was a story for someone else to illustrate!
So I'm taking another approach - looking for my characters before getting serious about the text. (I have an idea about the story though)
