This is an NGADM Round 1 review.
The song instantly starts with quite a beautiful melody that I think might be at least partially inspired by the fantastic Lord of the Rings main motif (although might not be). The piano sound is very soothing as well, and the strings are wonderfully warm! The whole atmosphere of this is very uplifting and I'm relieved to hear that you put in dynamic changes too, with smooth transitions on the whole (although I think you hyped up the 2:29 transition a bit too much since what followed ended up sounding a tad bit anticlimactic). This is great cinematic stuff that certainly has film score qualities to it.
There are a few issues scattered throughout the song, most of which were already mentioned by johnfn. The piano's quick notes at 2:07's and 3:36's section felt out of place, and the mix gets very muddy and full up during the louder sections, doubtlessly due to you having such massive and loud string chords playing. Another tiny complaint is that I'm not a big fan of your minor chord choice at 1:43 and all similar occurrences (but this is probably personal preference). One final problem this track has, however, is that apart from the main melody (which might have been focused on a bit too much for comfort), the melodic content in this track is a bit unsatisfactory.
That being said, this was a fantastic listening experience on the whole. Good job.
