Looking closely at CZ, you can make out a couple of interesting joint articulation points. Of course there is the standard shoulder point, but there appears to be one above the bicep, because one arm is rotated a bit more than the other. There is that awesome elbow joint that looks like a swivel bolt, but there's also wrist apparently; you can see the shadow between the hand and the forearm. I'm going for about 4 of these for various scenes. Well done Hasbro!
Edit: I think I could make the Luke work if I can rip off the fabric and fill any holes caused by the ridiculously oversized belt. A couple of poses would look pretty good I think, but those thinly sculpted boot ankles really accentuate the big feet.
