the basic technique was to find find a piece of an image i could use and warp and size it into shape. use hue and saturation to match the colors and then blend them in by using eraser arount the edges. sometimes the using healing brush tool to blend. if the image wasnt quite right it gets more compliced like with the eyes from http://www.sxc.hu/photo/1179488 i had to compy bits of the pupils and paste them on to make a full circle and place then where i want them.
