School Buses: Crunchy on the Outside, Soft on the Inside
A couple years ago I illustrated a series of educational children's books about dinosaurs; it was a great project! I got paid to draw Tyrannosaurus Rex, Spinosaurus and my long-time favorite, Stegosaurus (among others).
This Allosaurus never made it out of sketch phase. Everyone involved decided that a child running for its life was not exactly appropriate for the target age.
