The RT's sounds great and the strings so support the vocal that I'd suggest (as did Gibson) to just toss the drums. The song is so airy and delicate that the drums just seem a bit heavy even when down in the mix. I'm probably the odd person out as I've done a lot of songs w/o drums and am used to the feel.

I wouldn't change another thing. You did a wonderful job of surrounding a great vocal with an effective just right lush arrangement. Very, very, nice!
