Thanks to Robin explaining on Tumblr how he did the crying blood effect for Jack, I figured it out.

It was.
Very confusing.

(Bless this person who asked the question)

But now I know all about tracking and masking layers.

Knowledge is power.
(I still got a lot to learn, oof. But I'm determined.)

Also this effect will come in handy with the melody meme~
((After I finish two other memes I've already started.))

HAHA NO ART

DEAL WITH IT
