Well done
The few Futurama episodes I watched were in French language... so naturally I can't tell if you were close to the original voices but reading the previous reviews it would seem you did a great job, kudos. But you have a large voices range and it's easy to distinguish the different characters, the intonations were good and lively.
Although it was better than in your first submission, the sound quality could have been better in two points: the audio was clipping a bit but can fix it buying a better mic. And you could work on the equalization a bit (Audacity has an equalizer), adding more bass frequencies for instance to make the sound fuller. This can also be fixed if you get a better mic. What mic are you using in that piece?
Good job overall ;).
