I think you have a good base for a lipsync! One thing to note about some phonemes is that the mouth may have less vertical distance between the lips, but the corners of the mouth stretch out to compensate, for "s" sounds, like "ssssssnake." It might help to even exaggerate the mouth shapes a bit so that the sounds read a bit clearer, then you can always take it down a notch. Additionally, I'm not sure if you had the animation in stepped mode or just keyed out each individual mouth pose frame by frame, but I find it helps if you leave a gap in between for the program to automatically interpolate between the frames to make the transitions between the mouth shapes more smooth instead of having it look snappy.

One last thing is to play with different parts of the face as well; a lot of emotion in speaking is carried through our gestures, especially our facial features. Look into different ways that positioning the eyebrow can change the tone and mood of our character, as well as accompanying secondary motions that can help paint a better picture!

Edwin Rodriguez:

Nice work on the lip sync, just needs more polish

Richard Adams:

Lip syncing and facial expressiveness decently done. Body is much too static.

Kyra Simone:

Ah, either a stepped animation or a lower framerate, guessing the former. Reviewing 2D principles will help with this... right now it needs to be more exaggerated and the body seems stilted. Look at Spiderverse for inspiration on lower-framerate 3D, or alternatively some stop-motion film!
