Both versions, actually. I kinda made this one night when I was bored and because I love Aeris' character so much, I made an AMV showing just how much. I've made friends cry to this. No joke. I put so much effort into this, and it came out great.
The basic idea was to show that Cloud still grieves at the loss of Aeris and that he can't really go on without her.
The song is "My Immortal" by Evanescence. Yes, I know. It's overused, but I felt the lyrics felt what I was aiming for VERY well.
Final Fantasy VII: The Man Who Still Grieves <---First version, with FF7 clips mainly and only trailer shots from FF7: AC
Final Fantasy VII/Advent Children: The Man Who Still Grieves #RELOAD <---- RELOAD version, made shortly after the release of AC. The more powerful of the two videos, in my opinion.
I hope you'll all enjoy them ^_^.
