For me there was nothing wrong with the audio, except when the bird gets angry with the guy in a cap and screams, then I would have had him scream more distorted, but that´s more with the voice acting which is otherwise perfect =)
The animation is incredibly stunning and well done, I can´t stop laughing at that baby with the eyes! XDXD He is the most funny character I have seen in 15 years. Thanks for the laughs and can´t WAIT FOR EPISODE 2! =D
