Very awkward, long, and drawn out. The comedic timing is amateurish, the voices are obnoxious, and the jokes are uninspired.
I know how it must feel when you're an animator and you take a long time drawing something and you want to leave it on the screen for as long as possible so everybody gets a good long look at it, but this really needs to be faster paced. Your 6 minute cartoon feels like it's 20 minutes. The best part was the first minute when things were happening all at once and it threw stuff in your face and didn't waste your time.
I would say the quintessential sci-fi comedy cartoon is Futurama, which is saturated with jokes. It's just funny funny funny over and over again with a gag every few seconds and no boring gaps in between. Yeah, that's hard to do. But you gotta make sure you try to throw as many gags at your audience as possible and find every opportunity to do so. And don't milk just one joke because there's a chance it was never funny in the first place. The red button thing was groan-worthy. I feel like you had maybe 2 minutes worth of quality content, so drawing it out to 6 minutes makes your audience just wanna leave.
So... make the characters charming and likable, pick up the pace, don't reuse jokes, don't draw things out, and be original and inspired.
