My one criticism:
Circle-tool pool of blood. Next time just shape-tween between two hand drawn puddles, so even if it's a simple as fuck shape, it'll look more organic.
That's seriously my only criticism. There's not another thing here I would've done differently. The cuts back and forth to the Youtube-Commenter's gargling were timed beautifully, and over all I found this inspiring and great to look at.
Stop making me love you, Hadel. <3
