I think it would be unfair if I couldn't enter! Work for me is designing corporate logos, business cards, letterheads and web sites and I consider this oppotunity to make some "ART" which is related to my passion of cars (Skylines!) very far from what I do for "work". And yes, photoshop is fun, and fairly intuitive (a brush is a brush, a pencil and pencil etc) so everyone who has photoshop should have a bash at it. I never read the book/manuals either. I think the creators of Photoshop have created an absolute monster of a program. I doubt that the creators could ever have predicted some of the amazing imagery that people have created with their program.
I'm super chuffed with these entries. I love all of them!
