Again?
You submitted the same thing twice with little improvement. Sorry it got blammed the first time, I actually thought it would pass, but with a low score though. Maybe this one will do better. But, if not, try doing some big improvements as opposed to little ones.
Things you might do:
Art - Assuming you are the voice actor, then you are clearly young and your recent submissions show you are a beginning artist. This submission has improved over your other three, so a little bit more and you'll be great.
Story - I don't care to see Pac-Man Jr. fall in love with a pebble, but that's me. The flow of the story was good, and the joke although mediocre fit with the story.
Ending - Change it. Those kind of crossovers are annoying and bland. And for me, even when mainstream television does that to their own show, I don't really like it. It detracts from the original story.
Music - Fit the story perfectly, and sound was great, nothing to worry about there.
Voice Acting - Voice was clear, and your voice fit for a PM Jr. voice, but you need to improve your annunciation and dialect a little bit so it doesn't sound like you are reading from a script.
Overall - 4. You get a minus because you submitted it twice with little changes, but the previous effort still showed.
