Very relaxing and serene (with the exception of the battle theme). The battle theme was impressively produced, with big orchestral drums transitioning into trap style percussion and then switching back. Good definition on the drums, punchy and stood out very well.
The entire soundtrack is slightly heavy on the reverb, but it's not that a big deal with the exception of 0:54 on the first track. The reverb gets out of hand when the pianos block chords change and it gets very muddy. It's a good idea to put a highpass on the reverb when the low end starts to build up like that. Additional ways to fix it are to change the pianos voicing to more open chords (eg. for a C major chord, instead of C E G go with C G E), reduce the reverb time or the wet amount.
Enjoyable soundtrack overall, good work!
