Damian Gascoigne is an Illustrator / Filmmaker who has been working for 25 years. He loves to observe and he will use anything around him as inspiration [people, animals, interesting marks and drawings] He is constantly taking photographs of his influences. A large amount of his inspirations to his work comes from his surrounding. He See's himself as a 'bit of a snoop' as if he's senses something interesting around he will creep around to experience it and then maybe go on to use it in is illustration.
I myself would not work in the same way as Damian Gascoigne as I'm not particularly interested in making moving images, however I do think we have have the same way of taking influence as I also love to observe those around me.
