Disclaimer - Unlike many artists, I post my successful paintings as well as my not-so-successful ones. These sketches are by no means masterpieces, but they were fun.
I usually begin by getting the shape of the head in then move on to placing features. I wondered what it would be like to begin by painting eyes, the build out from there. What a strange feeling it is to have a face staring out at me while I'm trying to paint. I think you'll see what I mean.
