This is what is referred to as "Homage" not "Parod

Not a failure, but you need to label things correctly.

Your comment confused me a little.

Great animation to match the original opening for Death Note, but when you said (Flash Parody) I expected you to make fun of Death Note opening as what a parody does. I think Death Note is awesome, but you should try to make more original stuff. For example make a small flash of someone finding a death note and something funny happens. that's more of a parody, rather then imitating the actual anime. Still good though.

How is this a parody?

It's the death note opening animated in your style, That's not a parody the only reason I'm not flagging this as stolen is because you at least animated the opening your self. Figure out what a parody is and do it again.
