There you go!
This is my first time doing puppetry in Flash so the organization of it all is really messy. I hope you can navigate regardless.
Thank you so much!
Hi again, mate,
Unfortunately, I can't give you one simple solution or even a simple answer.
The tween problems are caused by a combination of factors, the most important one being the terrible implementation of Layer Parenting and other issues such as rounding of calculations which accumulate and produce exponentially worse results further down the hierarchical chains.
I focused my investigation on the tween between frame 80 and 94 in your FLA as it looked simple enough to study with the same symbols on both ends.
I removed all layer parenting and re-registered the symbols, based on your Transformation points and the results instantly improved. You can see that here:

There are however multiple issues with the structure of your file which make it nearly impossible to be fixed.
They are fundamental.
For example your character timeline is unnecessarily complex - all facial features should be placed inside one head symbol on a synced timeline. You can have the back part of the hair separately behind the torso, but that is pretty much all that you need.
All variations of the mouth should be put inside a mouth container; all variations of upper arm should be frames inside upper arm container and so on.
Have a look at this article which I wrote some time ago:

You're obviously extremely talented and hard-working, that is why I want to give you the best advice I can.
To be able to really progress with cutouts in Flash you will need solid understanding of Symbol Registration and nesting.
Look into Smart Magnet Rigs. It is a much more polished and flexible system than Layer Parenting or Animate bones.
Very little can be done to save your file the way it is at the moment.
I don't want to give you suggestions as that will probably confuse you, and may not be what your teacher would approve.
I wish you luck and success in this profession as obviously you have all the necessary skills and talents!
