The voices and audio seemed rather quiet. The artstyle was ok, but the animation I feel can be improved. Consider adding more movements and gestures to your characters so they do not appear to move like stick figures.
One example was the part where the guy in glasses says "You can't see the moon [...]", at this point, you could have him make a gesture such as rolling his eyes, or having his head tilt and move slightly as he speaks so he appears more active and lively.
