Given that I liked it, is the lyrics yours? Speaking of which, in the context of writing a song, how did you approach the Verse/Chorus structure? I ask because, in my opinion, it lacks that immediacy characteristic of a light music song, that simplicity (or perhaps immediacy, indeed) in making one want to sing along right away.
What left a strong impression on me instead was the melody and the sonic atmosphere, pleasant and at times even elegant... so you have achieved those objectives... in fact, up to 0:50 it is very inspired, as is everything that derives from this material.
In a melodic context, I believe harmony doesn't win, and indeed the first piano interlude at 0:50 is centered as a harmonic context but melodically reprises almost nothing; for example, the subtle part at the second minute is much better.
The piano solo at 2:30... "distracts a lot".
In my opinion, today pop music revolves around two major components: the performer's voice and the video clip; the rest is obviously not a detail, but as Lupino says and as you demonstrate awareness of, you must master your Knowledge... which can come more to a musician. I guarantee that I greatly appreciated what I questioned just a moment ago, only because I wanted to evaluate them through the eyes of someone who has the current Pausini in their ears.
In my opinion, in a video where the pianist with the most "interesting mannerisms" caresses the keyboard, posing with a lost gaze and such amenities (you know Einaudi?), it gives off a strong sense to the average listener...
and allows you to "go all out" in the solo. But even the piano must "sing".
Anyway, this is just my opinion; I had the desire to listen to your song again, so... it's just that I don't know how much of a lyricist I am as a pop listener or rather, I have my own idea of pop which obviously cannot be universal.
