solid work
You did a good job. animations were good, sound was good, seems your japanese is coming along well (Though it is painfully obvious why you are studying the language :P). My only complaint is the humor wasnt really that good to me, but thats just my opinion.. im sure there are many others who would beg to differ. You have some talent, and keep up the good work.
one suggestion: (though it doesnt really count since im not a flash artist and could never make something this good)
try not to really so heavily on the japanese animation techniques as a method to drive your work.
