Very Soothing...
I love the overall tone of this song. The piano is a nice choice for the lead, and meshes well with the harmonies you created. They just go well together.
I like the playing style you are using with the piano. Rolling chords methodically in the right hand is always a nice change of pace. Then when the melody line comes in it really adds to the song. I'm not sure about the overall sound of the melody line though. Kinda odd, and I'm not sure it really fit well with the song. But this is only my opinion, so take it or leave it as you will.
I like the chord structure you are using. It isn't just a melody and bassline. There are real chords being played throughout this piece, and it adds that color that is no needed for a song like this. I could really just sit back and take in the world while listening to this song. Makes me want to lay out in the stars on a beautiful night.
The ending is kinda rough. You should work on that a little bit in my opinion. It just kinda dies, and that isn't really fitting for a song like this. Normally I am completely against fadeouts at the end of songs. But I think if you repeated the section around 1:20 and faded it out, it would have a wonderful effect.
It seems to me you might want to tweak your limiter a bit. It is causing phasing issues with the piano and harmonies in places. But overall really nice job here.
4/5 and 8/10 overall, because it is good. But it isn't quite perfect yet.
Best of luck on your future projects bud!
