Looks good, sounds fine, but something missing...
I thought it looked nice, clean and simple, it works well (looks a bit like some kids cartoons I've seen, though the content isn't quite kid-rated)
The music, what little there was sounded great, not intrusive or anything, just helped the movie.
The voice acting could have been a bit better but there are probably good reasons for this, plus it's still better than a lot of other stuff I've heard.
The only problem was the script, it didn't seem quite complete, like the jokes were either a strugle and couldn't quite come out right or just instant and not thought through enough. But that's just my opinion (and it is getting harder and harder to write original comedy)
and I'm British so my sense of humour's probably a little off anyway ;)
Overall I liked it, but I think it needs more work. Phew that seem a lot! Anyway, keep up the good work and I hope to see the next one soon (but don't rush it)
