The beginning is quite strong, transitioning from complete black to black and white and then to color, with significant changes in scenery. It quickly communicates the motivation of the daughter and advances the plot rapidly, establishing the narrative. I would say it's a great decision.
The mom crossing out the names in context of calling a bunch of other moms for her daughter. I feel it was a powerful scene, and communicating that she called a lot of moms through visuals is an excellent choice. "Otrogonamtias" is an interesting last name.
The many different changes in scenery is intriguing! The sound design complements your animation well.
The daughter, Lily, showing character motivation and wanting to know what she is, is good. The view of being in the dark about what happened to her and being in the mom's perspective is a good choice. The mother preparing for what's to come is scary, and the radio communication about a disaster coming is interesting; The dad, that's a very powerful monster but his control is primarily psychological.
The scene where the mom threatens to kill herself to get Lily's attention is interesting, and the monologue disclosing the character motivation Influence by the negative Influence by dad. I feel is communicated — Devourer of Sin.
I burst out laughing when the mom said that being supportive of Lily playing video games and even saying that it can be a career, even though she would prefer if she didn't, was very thoughtful indeed.
Conclusion of your film is very nice, excellently done. She is only human XD it's good they went home.
