I think you did well with the voices from what I could make out... the sound quality for the female could be improved quite a bit. I give you a 3 only because as far as voicing goes your microphone quality is a huge thing.

I can't comment on the inside joke really, But the second drawing of the girl is well done. I said it for your other video but I do reccomend better audio equipment. lol

This was very Impressive, so much so that I'm jealous lol, you presented it in a way that made me think this was from a professional voice help DVD. The only thing I had a problem with (And this is being nitpicky) was your Indian accent, not the accent itself, but I felt like I didn't get to hear enough of it to really judge it to the best of my ability. That's just me. But all in all, very impressive. lol

Your narration voice is superb, the only thing I suggest is removing the echo effect for the characters and just leaving it for the narrator, I felt the characterization you did for them was well beyond good enough for it to be stand alone without any editing effects.
