Hello rottoy! Lovely little reinterpretation! I'd carefully rework in real-time the Eq & countermelody a bit on the Horns (press stop, take a step back, and try/sing to find the best, maybe simplest, melodic contour), you could also play, [starting especially at 1:08, for continuity sake an added boom], and play in every 8/4 measure a bit more with the dynamics of all those chords underneath, you'll get that nice "Howard Shore-Lord Of the Rings" feel, but apart from that, great love was put into the playing of the forward instruments, and they sound really great, I'm sure if Hans takes the time to listen, he'll be pleasantly reminded of the great journey making this movie was!
Thanks for sharing!
Best,
-A.-
