Metasequoia modeler tutorials and Keynote translated plugins

[Creatura]

I've spent a couple of days working on this model and finally I'm done with it but when I try to animate it, it plays on my nerves!

I know how to setup bones and anchors (at least I think I do) and I've set it all up but when I move 1 bone it affects other parts which are not connected to it (this doesn't happen to pelvis and legs).



what might I be doing wrong?
I've checked all the anchor cubes and they are connected properly.
