I liked the composition, I liked the effect that Illustrator brushes give me for the lunar surface, but all the little tiny details that I would still have to do from this point on drove me back to traditional illustration. See all the segments on his space-suit arms? Each one needs a highlight and a shadow. And that's not including the shading on the rest of the alien, complementary splashes of color in the craters, details on the sand castles, reflections of the rings onto the dome of the spaceship... it could go on endlessly. All of which would be a lot more fun with a paintbrush.
So I did The Gingerbread Policeman. And the bear painting. And now the alphabet book. After that, there's the Christmas book to do first, but it's only a matter of time before you'll see some painted versions of the Little Green Riding Hood computer pics that I posted earlier.
