Weird Rigging (maybe skinning) problem

[deagle33]

thFully rigged head model after some skinning looks like this. Who knows what is the problem?

Is the geometry's history clean? Check to see if there's any non-deformer history and perhaps make sure that there are no keyframes on the vertices, etc. Also, if you could maybe post a bigger gif to see the hierarchy, sometimes there's a misplaced element and that can make things wonky.

check the skinning weights properly

you forgot to parent the Eye controls to the head.
