Some constructive critiscism,
The one I saw on youtube made by RNKN was better. Catchier song, Funnier animation, really captured the spirit of filthy frank. This? Not so much. FilthyFranks whole thing is about comedy and satire.
Your animation is too anime in the sense that the characters don't even look much like FilthyFrank besides their clothes and costume. Akin to an anime artist trying to draw fanart of a western character, like say, Frankie Foster from FHFIF only for it to look like some unrecognizable generic, overused-anime-style girl with red hair wearing a green hoodie and a purple skirt. Plus the whole scenario is TOO serious.
Don't get me wrong, your animation is pretty smooth and drawn incredibly well and I can appreciate all the work put into this, all that time must've been painstaking. I just think you could've done better if you adapted FF's style to your art instead of making the mistake many artists do where they adapt their art onto the style of whatever their parodying.
