Xenomorph model test

I was working on my project the other day and i came to a point which i had to make this alien face closeup , now i originally planned this to be frame by frame (haha ! i wrote the whole thing not just FBF!) BUT ,i was so tired after finishing that previous frame by frame sequance and the fact that i havent slept in two days now that made me decide to use tweening methood ,now i usally dont like using it for complexed motions but i guess it will do.

this model is made out of 5 parts (excloding the tea which i add later for my own personal resons) , the upper jaw and front of the head , the rear end of the head for the 3D like apearance , the lower jaw , the inside of the mouth with the side gums and the body piece.

this one looks jumpy because i've changed the model while i was doing this test , the inside of the mouth wasnt big enough for some of the movements but at the actual movie it will be good.
i wanted to add some music like the ones you hear in a royal palace and stuff but i couldnt find one quickly and cant be arsed to do a full net search for it, so there.

enjoy.
