Man the vocals are nothing short of great, but what's with your problem with f's below 500Hz?
It sounds like it's coming through a megaphone which makes everything sound crisp, but massively fatigueing. Why have you cut all the lo/mid and bass out of the piano? No need - it doesn't fight with the vox, especially since you have HP'd the vox so severely. Man this is great stuff that can just be sorted out with you starting by putting all the eq's back to flat and listening again and best of all comparing to a reference on your own monitors. This is great music, but not how most great music sounds .
PS Much as I love vintage warmer 2, over use also becomes fatigueing
