Here's what I'll send in...
Acting: Some personalities were more believable than others, and some seemed to be stuttering before saying the right words. I know most people don't talk very fluently but this seemed a little overdone, almost too improvised.
Fit: All voices were done well, and they fit their corresponding characters with almost stereotypical precision... in a good way though.
Originality: Even though it was an overused subject, the addictions were very unique, and it is quite entertaining to visualize these people's addictions.
Range: All characters have their own distinction, and it was pulled off quite nicely. I think two characters sounded a little too similar, but since the dialogue is so rapid-fire it's not too noticeable.
Mixing: (at first) There's nice background chatter, and the music fit nicely... I could hardly spot any pops or hard letters, and the volume was very even throughout the- (suddenly) FFFFFFFFFUUUUUUUCCKKK!!?! Take that goddamn cricket chirp out... I think my ears are bleeding!
I'm thinking your strong points were in the "Fit" & "Originality" categories.
I really dug the improv style of humor even though some lines were over-the-top, it still adds to the presentation.
