I wrotte to the guy and he answered:
I see so many Conan pieces that were hack and slash that I wanted to do a
bit more of a romantic version. Here is a little description about the
inspiration for the pose from my work in progress thread on the ZBrush
"You'll recognize the inspiration of the pose from Michelangelo's David. I
wanted something simple, but powerful. I altered the pose somewhat to
allow for him holding the sword in his left hand and holding the necklace
he gave to Valeria (his woman in the movie) in his right.
I thought the pose was kinda somewhat fitting (just a bit) since David
went on to become King of Israel and Conan went on to conquer and become
king by his own hand. But the pose also tells the story of him lamenting
over Valeria's death while seeking his revenge. That's interesting because
in the beginning of the movie he states that the best thing in life is "To
crush your enemies, see them driven before you, and to hear the
lamentations of the women." Yet, here he is on the receiving end...."
