In my original little sketch of this scene, the teacher looked way too mean. I know from all my visits to primary schools that the teachers are all lovely! So I redesigned her entirely, to try and make her look a little flustered and a bit cross, but still cuddly.
If you look closely at the sketch, you can see I was also playing with the idea of having multiple Sparkys within the same image, to get across the idea of him jumping round the room, crazy-quick. Although it's a fun idea, I decided against in the end, as this is already a pretty busy spread. I'll see what my art director at Gullane thinks when I'm all done.
