(Update: a reader has informed me that this is a statue of Hercules fighting Nessus, sculpted by Giambologna.) I found this amazing statue in one of my Google searches, but I can't find the name of the artist. This is Hercules fighting a centaur. I love that hand pressing against Hercules' chest. I want to use that hand.
So I went back to my reference photos and began piecing together arms and legs and torsos.
At this point Donato told me to stop obsessing over musculature and concentrate on the faces, since the faces are the most important thing-- that's where the viewer's eye will linger, and the emotion on the faces is what will make the painting.
So I went and drew emotive faces.
James Gurney came today to give a lecture. He walked around the studios and stopped to talk with me for a while. He said he loved those heads!
Several other people thought that these faces weren't expressive enough, so I turned on Youtube and got Tom Hiddleston's face and drew sad Loki and screaming Loki. That ought to be emotive enough.
In the end, I decided I really like that second pair of Thor and Loki heads. Those are the faces I'm going with. This is a moment of calm in the midst of the battle, when Thor has to decide if he really has the strength of will to bring that hammer down on Loki.
