I keep my modelling images natural, raw and often 'grungey', contrasting the artificiality of mainstream media imagery.
How can someone who makes Art that attacks the media and consumer society also produce modelling photos of himself? Well, the modelling images that I produce use no artificial lighting and no 'doctoring' on the computer. I produce images that display myself in an authentic way - the way Nature intended, as opposed to the fake and 'hyperreal' images that we are bombarded by from the mainstream media industries.
Don't let advertising make you feel insecure about your appearance. Don't resort to excessive amounts of make-up or plastic surgery. Just be happy with what God gave you. I know I am.
