Often, I will use faces that I find on the internet. I pick ones that have some kind of immediate emotional resonance to me. The bodies I build from live models in my studio. Lately, I have been moving toward the practice of making my work more like a traditional portrait by using a single person as the source for the entire figure, rather than taking a face from one figure, the body from another, the hair from a third, etc. This simplifies things, obviously. I think I am getting better at transforming a single figure into the being I am trying create, and I need to search around less for bits and pieces to construct the figure from.
