I designed this parts  after i had watched how you could moving  giraffe's neck !

I added some changes to the parts, so that they fit my animal movement.

Note:

Parts has made as prototype.

There is a problem about solid tool, i drew the head and  middle part but i can't make them solid.

And at the beginning of drawing, when we want to import pictures, i felt that there was no Symmetry, i tried to solve that but i couldn't. So could you please explain these step? maybe you can notice that .
