Kick ass! ROCK ON!
Yea, Black Sabbath's "War Pigs" does sync up really well with how you've done this movie thus far, just instead of Link being the War machine, I think that would be better suited for Ganon/Vaati/Agahim (idrk if I spelled his name correctly).
You might also be able to use "Snowblind" for an "Oracle Of Seasons" movie too.
"Iron Man" might work well with an Iron Knuckle and the big mid-dungeon boss in TP where you get the big iron ball.
And I also think that "Paranoid" would work better with young Link facing off against King Dodongo or Adult Link fighting Bongo Bongo, but, whatever, your call.
Still an awesome movie dude.
