Angel Beats Prototype! Help!

[Wrath192]

I don't think my last forum actually posted x.x either way. https://www.youtube.com/watch?v=oXS1XAvoApk This is my baseline for an AMV i currently am progressing on. I want to start doing SFX to it. im a scrub at SFX. but I hope I can consider myself an Above Amateur AMV maker. I really wanna try to get to the big leagues of AMV making one day. I love it as a hobby. I don't care how long it takes. My determination no matter how much I fail wont stop me from trying. Ideas what I could redo. is the song to outrageous? Is it to dull? If not what were the dull moments? Just looking for help in general. Help? plox !
