Sort of cheating on this. I was looking at the painting I did of my partner recently, done from one of the 'cut paper' series of digital portraits and I wondered about the one I did of myself. The original version was just the lined version with the line layer turned off, something I do a lot to amuse myself.  What my partner's portrait had going for it, I thought, was the VERY tight palette; four colors. The version I posted was all over the place. So I went back and played with what I had and managed to get this down to five. it think it works a lot better than the earlier version. It's very pink but so am I. This would also work as a large painting and perhaps it will be my next.
