Great start. My critiques are as follows:
1) Overall there was just a bit too much of the jiggle action dynamic, distracting in some ways.
2) Around frame 50, when baby juice falls, the fall could have indicated some forward motion. (Imagine: yourself running away in fear from the neighborhood bully and falling forward skinning your knee!)
3) After getting up- baby juice could have expressed more fear during the moment that it turned around. A pose indicating a strong sense of distress and urgency.
4) The moment baby juice gets to the wall, the opportunity was for the character to express dilemma (ie. character pressing back again the wall & squirming. Giving the audience a sense that there is absolutely no way out)
5) The script's antagonist or adversary could have stopped immediately once he realized that the baby juice was corned. A strong pose as if to say 'I've got you now!'. Then the adversary could have crouched lower with a stronger sense of determination. (victory is in site). Fingers could have been posed in much more sinister way.
The character sorta of looks like a string puppet with hands high and palms facing up. More attitude could have been conveyed in the adversary's character animation. It currently looks like a walking string puppet.
Keep up the great work. I will I will looking forward to your next work.
