Wow This one was a blast! I think the composition is amazing. I especially felt the transitions where super fluid. (1:11 was my favorite). In fact the only thing I have to say is that id wish the song moved just a tad bit "brighter" in sections. The epic and triumphant parts where spot on, the "serious not so serious" bit I was less convinced of. It sounds like BW and BW2 opt to go in to variations of the original PKM theme at point in the song.
If you arnt that hard stuck on being 1 to 1 then its already a bop IMO!
