Well done, if a bit pretentious
I really liked how stylized this cartoon was, and how you kept to your typical drawing style despite the fact that you were doing a lot of frame by frame work here- and hell, I like how it was animated for that matter.
My only qualm is with the plot. Or rather, how you treat it. As far as I see it, earthquake girl gets the order from the wealthy dude in charge of the architecture firm to start blowing shit up, and then she does it. She's insane, a force of nature unrestrained by reason- hence "earthquake girl" as a title for the movie. Then, after she's finished destroying the whole city, we see that the whole thing was orchestrated by this evil rich bastard who "loves his money" and who intends on profiting from this cataclysm. The message (and of course, I could be missing something here) is simple: rich people are evil and will do anything for money, even going so far as to be complicit, or even support, the loss of many human lives in order to make a profit.
I like this message. I agree with it. the only thing that bothers me here is the fact that you seem to obscure this message on purpose, devoting the majority of the movie to senseless violence and a string of red herrings which draw the attention away from the key plot points. Not only does this diminish the quality of the message, the moral of the story, as you put it, it makes you seem like you're just trying to show off, trying to make your movie seem more "deep" by making it hard to read into.
Whatever, regardless of my rather minor complaint, I love this movie, and I'd love to see you do some more long-term complicated animation like this in the future.
