I think everyone understands the title well enough - just aren't terribly interested in the models for the moment.
AS to fingerposing - all you have to do is rename the finger bones to the same names as valve using for their biped.
YOu need to have the hand bones as as well as the finger bones.
ValveBiped.bip01_L_Hand
ValveBiped.bip01_L_Finger0
ValveBiped.bip01_L_finger01
ValveBiped.bip01_L_finger02
(first letter is finger, second is digit (no number is first digit 0 is thumb, 4 is little finger)
That should help you out on the finger posing part. Models look good, although I always though Pit girl had a darker skin tone


I could however be wrong about it.
