I decided to go for broke with the self portrait and add some more layers using acrylics. This paper is a star in holding up to layers of mixed media and moisture. I'm impressed. Of course the layer of coloured pencil helps act as a base I'm sure.
Experimenting using multi media can lead to interesting effects and surprising results. This may still be tweaked a bit more, but for now I'm calling it done and moving on to the next piece. The drawing is about 7" x 12".
