Her illustrations, inspired by the classroom and playground, are drawn from memory after a hard day's teaching and most of them have one thing in common - adult figures appear only from the waist-down.
The idea, says Ms Brown, is to make them as child-led as possible.
"I have tried to show the world from their perspective," says the trained illustrator. "In the playground, there's so much going on every day."
After completing a degree in illustration, Ms Brown, 34, took a PGCE and began work as a primary teacher at Nantyffyllon School in Bridgend. She describes her experiences there, and at St David's Church-in-Wales Primary in Colwinston, as inspirational.
"I hope to get something published. The illustrations are labour-intensive, but now I've decided to go for it."
Ms Brown now works at HM Prison Parc in Bridgend three days a week, leading art classes with 16 to 18-year-olds. Her ultimate ambition is to write and illustrate her own children's books.
