Lila is Alvin People's partner and I created them both a year ago, after some inspiration at a creative cartooning work shop conducted by Kevin Burgemeestre. He has illustrated a couple of great children's books Bernard was a Bikie and Supa Dooper.
Unlike more conventional cartoons, I have draw up a series of very simply shaped body parts, heads, arms etc, Then I just assemble the illustration and scan them. If I need to draw extra bits, I draw them, cut them out, and add to the collage. I've found it a fun method and the freer simpler characters have developed a life of their own.
