I like it! The first beat was already grand. That orchestral feeling really helps to feel the grandness of the situation. When the violins (I guess?) join at 0:20 feels very good. And I love the (falsely) hopeful section at 0:55... and how it got destroyed at 1:10 ;). The theme gets a bit stale after you've heard it a while, but it definitely fits a final boss theme (especially with that hopeful section included)! Really nice :D
