Very well done
The extennt of this film and the effort you put into it is just amazing. I can tell it took you a long time to make this and i am impressed with the final product.
Through the flash i could tell you grew ass an artist. Your animation skills are great, but mabye the story could have been tweeked, cause howmany stories innclude a guy whos family died and wants revenge. Also the backgrounds were ok but mabye next time make your own or bitmap them because they seem kind of chheap through the hole flash.
I hope you keep creating more flashes and make a name for yourself, i love anime so dont stray off from that either.
