Please don't take this as an insult, but instead, me trying to help you and telling you how to fix some problems.
What was the point in asking people to right-click and press 'Play'? You already had a preloader there, so what's the point?
First of all, the audio isn't streamed. So if I scroll down or go to another tab, it'll lag. To fix this, put your audio on a separate layer and set it to 'Stream.' And then make a keyframe on that layer when it's finished.
The art style is sloppy and inconsistent. The biggest problem is his arm, and how it does not extend longer than the body, as normal proportions would. Sometimes the line quality would be squiggly and others, some parts didn't match some parts.
The animation also needed work, like when Jake sat down on the ground. He shouldn't be stuck on one pose and manually moved down. Actual animation utilizes arcs, or basic plans of movement.
I would have his leg extend, propel him forward momentarily, his other leg extend, and then sit down.
The voice acting wasn't that good, because Jake's voice was Finn's voice, but trying deliberately to sound deeper.
The actual parody shouldn't even be called a parody, merely an exaggerated state of the original characters attempting some sort of "shock" humor.
But it wasn't shocking. Once you see 100 other animations that are exactly like this, you'll see what I mean. A parody exaggerates certain points of the thing it is parodying, and basically serves as an indirect criticism of it.
Before you respond to this review, I have some things to say. In the case that you might have been thinking about responding to this with a "too long, didn't read," an "I don't care, other people liked it" or something, give this a read: if you sincerely want to improve, then reading all of the previously mentioned stuff would be necessary.
Even if you don't care and just want subscribers/fans, then fixing all of the previous stuff I mentioned would still be necessary, because even if somebody made a truly horrible animation, some people would still like it, while others don't. And if you fix what's actually wrong with it, you'll find that more people will like your animations, and even if they leave something like "this sucks," then that indicates you could have done something better.
