Nice...
It's nice, but I think there are a couple of things that may help you in advice... Nothing's wrong, you did good. It's just that it was a little slow for one thing... May I suggest speeding up the frames per second. And the music was burning my ears... Sorry, but maybe music from the game would serve to your advantage. And Sephiroth's sprites had a shadow under him in the air. You may also want to look into that... But good idea and nicely done! Looking forwards to seeing more from you!
