Space Invaders Tribal

This is my design for my future tattoo... It is based on a traditional space invader (in case you hadn't guessed )
What I did was I took the original pixel image from the game, and blew up half of it to take up approx. 1 sheet of A5 paper. I then lay another peice of paper over the top and used the pixel image as a sort of template for the design. Then I photographed it with my digicam (scanner is broken), and edited in photoshop to make it look all nice (and copy pasted it so it was whole, not just half an invader)
