Eh, it doesn't really say "Jedi Heroes" to me. And someone's commenting how it's pretty much exactly a track from Superman with just a few changes? And listening to that piece from Superman, he's right. You're just putting a Superman theme in Star Wars.

I know you won't take this suggestion, but I reallllly think you should at least heavily consider it: make the "Obi-Wan and Anakin Theme" a good-hearted, calm version of the "Battle of the Heroes" theme. Here are the pro's to that:

1. You have a Star Wars theme, not a Superman one.

2. The theme will no longer come out of nowhere during the final duel.

3. We'd be so used to hearing it so friendly and "good", that hearing it so apocalyptic with a choir while these brothers duel to the death would be extra heart-breaking.
