Well this vote is pretty much for the song.
Im surprised that this flash passed, but in the same sence im wondering where you aquired those special custom dance sprites. From the looks of your website and respounces, english isnt your 'best' language so ill keep this short.
Things to help you :
1) when tracing a picture/sprite set everything to"1,1,1,many corners" and the sprites will come out cleaner.
2) line up the sprites! the animation just doesnt flow unless they line up. simple effort required.
so in the end, all i really want to know is where you got some of those sprites.
