The highscoring is all credited to your ability to animate frame-by-frame very cleanly. I think I read somewhere that you have a tablet? - That would explain it. So, if I were you, I would use this talent to it's full extent. I'm not exactly sure how to do that, but you have to have the following points:
- Good concept
- Well done and clean animation
- Good voice acting. (With an average microphone that doesn't crack)
- Background music
- Full colour
And I think you'd be set! Now, I'm not trying to make you feel obligated to do so, but I'm sure it would be a success if you really put your mind to it. Good luck, though!
