Hi
Very nice song. I also like the piano at the beginning, it belongs there. Good guitars, organs and vocals.
Maybe the guitar at 2:21 needs more processing (delay ?) or pan it more to the right like the one at 2:55 is paned to the left to create a stereo effect.
Also, maybe less reverb and/or release on the piano at 3:53. That sound fits well at the beginning of the song when the piano is alone but it's too heavy when it's mixed with the rest of the song. It's a good idea to bring back the piano at that moment, it's just that the sound must be adjusted to fit in the mix.
