Fuck the haters
Clerks is nothing like this except it's in a store and it's black and white. OMFG, blatant rip-off (not).
I enjoyed this, although a little more plot coherency and character development might make for a better toon, hell maybe even a series. Possibly some better designed backgrounds, I couldnt' always tell what I was looking at.
I liked the characters themselves though. the silly eurotrash guy trying to buy "super fuckin' donkey balls 2" or whatever, I LOL'd at that! Nice use of color as well, to accent things here or there amongst all teh black and white. the sound was phenominal, and the jokes where good when they didnt' seem like they where inside jokes that I wouldn't understand.
I believe you have a good basis for a series here, with a little polishing. You should go for it!
