I got a really weird 90's saturday toon vibe from the intro, which is actually pretty good. It had decent story, although maybe you dragged it on for too long.
That Vertrum thunder joke was probably used WAAYY too much past the point of it being funny and just getting annoying and time-consuming.
The writing could've been way better, without so many pauses and reiterations of the same thing. The voice acting was... Ehh. Practice on enunciating things better, so everybody can understand every word perfectly. The accents weren't really bad actually. Good.
The animation. Work on it. It's better than most people's first animation I've seen but don't let it stop you there. Just keep animating. Eventually you'll get better at it. Also practice drawing. Your aim is to make your next animation better than this one. Try to surpass yourself that way. Good luck.
