I like how you placed your own twist onto your drawings of Homer simpson and Peter griffin.
The voice impressions of each character were bad and laughable.
The bad impressions add an extra layer of comedy to this submission.
The way homer said, "Doh" was very funny.
I don't get your slenderman references because of my lack of knowledge about that video game.
I would have liked to see more lively poses in your animation.
Peter and homer just stood there.
Most of the humor of that scene needed the voice acting.
Practice creating more dynamic poses for your characters.
The slender man section of your movie had much more visually appealing animation.
The slender man section shown a lot more experimentation with the drawings.
You could have done more experimentation in the familyguy/simpsons section as well.
Play around with the colored outlines, backgrounds, drawing style, ect.
Just be sure to have fun playing around with all of the visual elements inside your cartoon.
You created a funny cartoon but with some more playing around with the animation.
You can also make the silly cartoon a bit more visually engaging.
Keep animating and always try new things.
