it wouldn't be consistent with the other 'hinges' if it had just one finger, I guess. I could remove it, but I'm trying to be faithful to the original. Nice catch though :) If you notice, no hand goes into the NW and SE position either.
i hadn't thought at look at the orignal - your fingers move differently! i prefer your movement, although i think the original has a slightly more balanced look (fatter fingers). you seem to be using a regular pattern of movement - have you considered choosing which finger to move at random, so that the movement varies more?
[edit obviously i don't mean that the fingers move at random, but since you have two fingers on a hinge you have a choice when it comes to changing how they are arranged]
