This is very neat. I like the chord progressions you used with the choirs. It oddly reminds me of some of the music in Steven Universe. Gives me a heavy nostalgic vibe.
In the second half, I like how the pace kicked up a bit and slowly died out into the enchanting choral melody. This is really beautiful and you can tell it was made to spark emotion. The random tubular bell at the end was a funny addition, but it worked well.
As I said before, this song feels really nostalgic, which is honestly perfectly fitting with the name "remembrance" lol. However, there is just one thing I have to mention about the overall song. It's very quiet. I had to put my volume up really high to get it at a comfortable listening level. Turned it up to around 90.
Usually, I add dynamic plugins like Maximus or Soundgoodizer to increase the volume of my work, but you're not on FL anymore, so I'm not too sure what you've got there. But it's not a big deal, the listener can always turn up their volume, but it could possibly turn away some people from listening to it.
It's odd because, in your preview, it was a normal volume. Perhaps there was an exporting issue?
Anyway, I'm sorry I took so long to discover this. Uni started for me 2 weeks ago and I'm still coping with the sudden increase in workload. I'll try to check newgrounds more often, only takes me a few minutes.
