Nice. It does add depth to the original idea. The timpani is a bit too dominant at the point where only a single woodwind is heard, but the return to the string arrangement comes as a relief, and the english horn is used very effectively. And the end made me think: indeed, that's how it's got to end. Good work.
I really enjoyed the listen. Nice contrast in the sections, especially bringing it way down to the flute and cor solos. Overall, very dramatic and broad. I had the advantage of hearing th later version so I think the Timpani is just right (cool ending!) Nice mix and not too much reverb ... just right.
