It needs voice actors. Also it would be a good idea to practice on background / environment art, because most of the time it's just a flat color, and sometimes that can lead to confusion in staging, where characters are in relation to each other, and such.
You got a great ear for setting the tone with music selections, but sometimes its really loud. But when it's literally between the music and the occasional sound effect, there's not a whole lot of opportunity to become practiced at audio balancing. Once you get voicework involved, I think you'll have a lot of fun with using audio balancing to help dictate the pace of your cartoons. Utilizing beats of silence to help punch up a gag or facilitate tension and other fun stuff.
The ambition is there, it's really evident. There's lots of fun moments that are super distinct in this that I liked, like when the cat gave that menacing grin before biting the dudes arm off. And you got the thing done! This didn't seem unfinished. But with that, there's also a lot of room to grow, so when you come back with the next installment, come back stronger! Do some research and practice on a fun one-off experimenting with new things that'll advance your understanding of animation, and boost your knowledge of the labor that goes into making funny and cool cartoons.
