I agree with jnry3
Sick as hell song, as always. Your piano melodies always seem to be extremely touching, haha.
But jnry3 is right; there really isn't any sub-sonic frequencies to complete the fullness of this song, and your mid-high freq sounds are interfering with the low-end (btw, the Spectrum visualization acts like well.. a spectrum haha). The spectrum shows that the piano is acting in the low-freq range, when it should be around mid-high freq.
So yeah, it could use some simple EQing, but nothing that's TOO difficult to fix.
Nice job dude, this is an amazing track. A 5 for you. :P
