About the bad cartoon
Movie was awesome, yes the voice could be improved, but I think "funny" voice was what fitted in that movie, it's far from "these pancakes are tiny" so even if their "matter of fact" voice works well in THAT movie, it wouldn't have the same effect in yours (someone below me suggested that, so I just add my little personnal touch ;p)
And for the guy who said "this was like a bad cartoon. the jokes were like a bad cartoon how he flew through all the factories with inconvenient stuff but other than that you did an ok job for a story about a sandwich." well he's totally wrong: these cartoons are GREAT and you call them the Looney Tunes! That little allusion to them with the flying soda can was really nice ;)
Even if the voices were a bit annoying and the animation lacking of fluidity, the jokes were perfect: one thing: you don't see the bear's arm in the sandwich until he discovers it (I think so) but you clearly see the tiny spears in the fries, so even if it kinda follow some logic, it completely blew the punch for me about the spears.
