I got the reference pic off a site on the net. I approached this portrait in the exact same way that i would be setting out to do it as a tattoo. First i printed the image out in the size i want, then as you would to make your stencil, i used my lightbox to fineline all the the appropriate lines/areas that i need to use as guidelines to know where the shaded and light areas need to be. Then as you would tattoo with your machine, i shaded with my pencil. I changed a few things here and there, the same as you would when tattooing as very small details etc will not make it as a tattoo ( as long as you dont change any major important features it will be fine).Where did you get the reference for your portrait?did you freehand it or trace it from a photograph?
