Congratulations Sunny. This is now my favourite song. I love the whole vibe of the song. The horns and cello parts are awesome. Great choice of instruments and arrangement.
Like Andy said, it has a Beatlesque feel to it.
I think the song has a lot of warmth (I am listening on headphones right now). My only criticism would be about the bass. It sounds to harsh for me. Almost a slap bass with crunch? I would maybe try a softer/warmer bass track. I think that would sit in the mix better. And although the drums are good, it seems to me like something could enhance them. I like the kick a lot. I think the snare might sound too tinny to me.
Please take my advice with a grain of salt. I am certainly no expert.
Again, great song and I absolutely love it.
Cheers,
Chad
