Very dreamy piece. starting at about 1:21, there's a sense of intimacy. I hear this and I think about two lovers in a high floor of a hotel room looking over a sunset, until about 2:40, when night hits, and the scene continues at 3:14.
I realize this imagery may come across as esoteric, but the important thing is your description matches the song; it definitely makes me want to relax.
I just have a couple of notes. First, the mixing is a little quiet. I suggest using compression/limiting plugins and/or normalization to increase the volume. This is so the listener doesn't feel the need to change the volume specifically for this song and then change it back with other songs.
The only other thing is the genre of this song to me fits more with dreamy electronic music or a chill hip-hop beat rather than strictly classical music. I think it would be better if you changed the genre to fit better with your style of music. Metaphorically speaking, if you expected to get Diet Coke but got root beer, neither is necessarily bad but you didn't get what you expected. Likewise, If someone looked at the genre and saw "Classical" they might think orchestral music, which this isn't. It can affect the ratings people give you and may influence other's reviews of your work.
I hope this helps. :)
