This piece reminds me of my highschool years, a music teacher actually gave me a copy of the piece to learn. It needs more flowing tempo, at the moment there seems to be some hiccups which are meant to be rubato effects but they sound like you are hitting a bump (usually just before when LH plays their lowest bass note, sometimes you hit that bass note right on time, but then decide to pause before you strike the next chord, almost as if you where searching for the chord or sight reading it). This effect has its place, but over doing it sounds funny.
You may want to broaden the climax near the middle, think, longer notes, and bigger, you need to rethink the expression and make changes sound a little more obvious, especially the calmness and serenity that follows after middle climax.
Try not to make the LH chords (following the low bass) sound too "choppy" (but that could be the digital).
Not bad at all! Good work
