Seriously? [review for score balance]
Well, this piece has nothing added to it, compared to the rest of the series, so there was no chance of getting a better score from me. Yes, you have done some plot (Doodle was going to his Kung Fu lesson), but we never saw him learning anything.
While attempting poorly to do Kung Fu might have been worse, I'm not so sure. Perhaps having things in there, such as whatever katas that you think would be required in Kung Fu lessons would have been helpful. Animating them would certainly give the episode more depth.
Backgrounds have been added in places, which is nice, though I would stress that if you're going to add them, make sure that you add background to every scene.
The drawing of Doodle does fit with the way that you've got the white loose fitting martial arts dress, but the massive gap in the middle, exposing Doodle's midriff was unnecessary. Cover that up, try to take care of additional lines where they should be erased and you'll get a good looking piece.
Finally, subtitles, to go with the vocals would also help - I'll suggest the standard black stripe across the bottom of the screen, with white writing for the subtitles.

try to make the characters really talk, and use more animation.
