It was definitely a good idea to make a longer song, I think you really tried hard with the chord progressions and it payed off. I really like how the melodies "play around" or "interact" with each other, and you definitely did the inro-drop-build-up-bridge-drop-outro thing. The other review said that there was a lack of bass in the second half which is kind of true but I don't think it affects the song to much. The only thing I think you need to improve on is mixing - the piano is a bit too loud. Other than that, great song, keep it up! 95/100
Sound Design: 9/10 - This song doesn't have your usual sounds but don't think that's a problem, you tried adding piano and I think it turned out well. The only thing you need to work on sound design wise is the mixing.
Composition: 10/10 - You distinguished the different sections of the song, and the melodies work really well on top of each other. Gud stuff!
Atmosphere: 10/10 - Like most of your songs, I can imagine a scenario in a game or movie. For this one it's someone standing atop a windy mountain.
