First and foremost: This is awfully quiet. It's an inconvenience to the listener, and no, it doesn't pass as "dynamics" in this case :( Not that big a deal if one can afford to triple that volume, i.e. nothing is going on in the background, or one's just focusing on listening to this track, but it's bad otherwise.

You replaced the echo-effect in the original track with a reverb. It's not a bad choice really. GBA didn't really have a reverb-effect, which is what I believe Shogo Sakai would have gone for is there was one.

Captures the feeling really nicely. Not much to gripe about really :)

Overall, there's not much to say about this honestly. It's a well crafted piano remix about a great track. It's fine sound-wise, but to hear this, one has to triple the volume, which is an inconvenience. Just a quick amplification in Audacity or something would do wonders.

Really enjoyed this. Very lucid...
