Small update: re-posed and painted the commander figure.
All german HL tanks come with the same commander figure in the same pose, and since that would turn out boring I decided to try my hand at re-posing my JP's commander figure. The pose might looks very similar to the original pose, but I had to cut both arms in three places, file away excess material and do some minor sculpting with green stuff to get them to look good enough in this new pose, leisurely holding some binocs in front of him as if he'd just used them.
As for painting, my Pz IV's commander figure is painted in SS black, and I wanted to mix things up a bit, so I decided to apply a camo scheme to my JP's commander figure. And a moustache. All rockin' men rock rockin' staches. .... Hey, my Pz IV's commander has a fat cigar, so why not a 'stache on this guy?
I used this picture as inspiration / basis for my commander's camouflage scheme:
I have no idea how historically accurate it is, but it certainly looks ace, and I'm not a rivet-counter to begin with.
So without further ado, here's Fritz Baumgartner:
PS #1: If you value your eyesight, don't paint a whole figure with small camouflage in one sitting. x.x
PS #2: If you disagree with my assessment that all rockin' men rock rockin' staches, too bad. I've got a beard, which gives me license to say that.
PS #3: ... Yes, that seems to be the correct location for the commander. As far as I can figure out, this is where everyone sits in a JP:

JagdPanther / Leopard 2A6 / StuG Ausf. G / KV-2 / M4A3A4 / MTLB / 2.5 ton truck 6x6
