Facial Animation (Not Rendered)

This is one of my animation projects done by me. I am trying to learn 3D Animation. This is for my portfolio. I am just a beginner in animation. Would be great to get critiqued.

I want to improve my animations by a lot. I am not where i want to be skill wise. Open for ideas on animation.

Thanks!!
