Lachlan showed the class some of his rough drawings for a new idea he is working that involves dinosaurs! See some of the artwork here: http://lach-land.blogspot.com.au/
At the end he draw a huge dragon on the floor and the whole class got to colour and add their own monsters.
Lachlan used to specialise in animation for games, and used to work at a games company as a concept artist. He illustrated the covers for the Robert Irwin Dinosaur Hunter series as well as others. His books include: Wombat goes racing, Wombat goes surfing, Dinosaur Rocks, and A very wombat Christmas.
