I'm sorry if this sounds overly negative because I have a lot of suggestions, I actually like the song, I really do! Okay, here goes!
- The bass is almost inaudible when I listen to the song with my laptop speakers but is almost too loud when I listen to the song with headphones, maybe you should tweak the mix a little.
- I really like the intro riff but my ears didn't really know what to make it when I listened to it for the first time, I assume that it's intentional that the root notes of the two chords the riff is based on are left out but maybe you should put them back in, it sounded downright bad to me at first
- Not sure if I like the fretless during the acoustic break and the filtered drums near the end (I really love the ending of the song, though!), they make the song sound a tad overproduced.
