I think you got the pose from the Terminator in the Forgeworld book: Imperial Armor Volume Four: The Anphelion Project. I like it because it make him look like he is getting ready to bring up his Lighting Claws to strike at some unseen foe.
@ Ali: I want to like this, as the coloring is A+, however, the pose seems... off, somehow. I think it's that he appears to be off balance, and the feet aren't defined as been as, um... flat as they should be. It almost looks like he's leaping. Still, like I said, A+ on the coloring, it's really ace.
