Here's an inspirational story of an artist who has created a niche for himself and is exploiting it intelligently and with determination. Artist Dave Devries takes childrens' drawings of monsters and turns them into finished artwork. Out of this has come a book, a poster (left), a presentation for elementary schools, another presentation for art students, and he's working on more books and lots of other ideas.
His website is www.themonsterengine.com and there's an entertaining short film about his work and plans here. Whether or not, like me, you're into drawing and cartooning, his story is a great example of how a creative person can combine talent and good marketing instincts.
