Great review! Izanagi's Theme was one of my favourites out of the character-centric tracks, but the ones you chose are all good, too.

Energy Breaker is one of my favourite soundtracks from a Neverland game (I usually alternate between that and Lufia 2), so I look forward to your next review!

On the topic of Energy Breaker, I'm not sure if you've found them already, but the 2006 soundtrack has a few arranged tracks that I think are hard to find. Here are the links (if you haven't listened to them already):

About recommending other RPG music, you might like Lunar: Silver Star Complete (PS1) or Harmony (PSP; has higher quality instruments)? It was composed by Noriyuki Iwadare, who also worked on Ace Attorney (which you mentioned before).

(Sorry about spamming so many links, haha. The last two might give a good idea of whether you'd like Lunar's soundtrack, if you haven't listened to it already.)

Edit: Before I forget, it might be worth mentioning that Yukio Nakajima speaks English (it's probably worth trying to use simple language since it'll be easier for him, with English not being his native language), and I think he'll be happy to see your review once it's written.
