Hard to say if it's good or bad...
Your animation is great, your style is unique...but your voice acting is rubbish. That's not to say the voices themselves are bad, but they're all different volumes and degrees of sharpness. Not only that, but the tone the actors use doesn't sound dynamic; it sounds too much like a rehearsed act being read off a script instead of a true, captivating presentation. It doesn't sound "in-character."
If you use an audio editing program like Audacity, you can alter the levels of volume so that all the voices sound the same; that way people don't have to crank up their volume to hear one person talk, only to have to hastily wind it back down because the next person's voice is 20 decibels louder. That by itself would be a big improvement. As for sharpness, that depends on the microphone being used; find people with better mics or just ditch voice-acting. Also, a word to the voice actors themselves: practice tones to match the setting and the mood.
tl;dr: Work on voice acting and you'll have a decent movie.
