It always takes courage to do your voice overs. You might want to work on volume balance, screaming into the mic often distorts the sounds. You also want to spend more time on your script. The jokes were a bit forced and it felt like you were fitting in "stupid B" as often as you could just becuase you could. The overall continuity was a bit off, though for just 4 random characters I suppose that's a challenge anyways. Good luck on future endevours.
