2 and I'll tell you why...
For a first animation, yerh it was pretty good but I'm sure I've seen the same kind of flash before
My advice would be to get yourself some sort of microphone or even to just add effects from a SFX website, Take your time with a flash (A great flash can take weeks if not months) and finally, try make it original man. Something no ones seen before, that's what grabs the viewers by the nads and gets you your 10 stars.
Hope this helped, dude
