Beautifully Writen
One thing I really liked about the entire song was the textures of the piece. I found it really peaceful soothing, relaxing and very deep. Textureis always a very difficult to achieve and I think you have mastered it. Love the piano. Those notes in the development came out terrifically.
The song was great but you could add a few more ambient sounds/ melodies throughout the piece (1:44) like you did at just to give it an effect as more natural piece. I also found the slight pauses to be a little awkward. Maybe echo some strings or something. Just personal opinons.
Overall great song. Keep it up! :)
