I decided to try playing with an image the other night. I did some coloring, tinting, softening, mosaic, and other things. I did 8 different variations on this image:

Changed the background

Changed the background | Softened her edges

Blurred the rocks - background and foreground

Tinted the background

Random tinting on background | Tiled part of image

Tiled part of image | Twisted tiles | Left her untouched

Tiled portions of image and laid tiles at angles
