As a fandom work I find this hard to comment on.
Like for your audience, and the audience of the fandom this is probably very legit.
It's nice seeing people have passion, and you definitely made some cool choices with presentation.
The shark pope was pretty funny visually, and you used some great transitions and animation tricks to make it flow.
Like the not having to draw the shark because it was being held to the sun made sense in the shot, with nice references to fishing and such, but also saved you alot of detail work
Keep working at it, and thanks for making this.
