Pros: An interesting chord progression, not cookie-cutter by any stretch of the imagination. Your voice is appealing as always, although there will be a con to it (see below). This sounds like, with some polish, it could be the kinda song that plays at the end of 'Grey Anatomy' or something.
cons - as pleasing as your voice is, you missed quite a few notes..which with such an intimate song is really dangerous of making me tune right out. I think i read you were pressed for time, so kudos for getting it in, just hopefully next fight you can really let your voice shine by singing on key a bit more. It seemed like you were making the melody up as you went...kinda searching for notes sometimes.
The Handclaps were: Ghastly. Very very aware that it was an add-on-cause-you-had-to (as were most people i think...including me) but i think having them go throughout was a little mistake.
Summary: It was an interesting song, and there were parts that were nice, parts that were boring, but i think it will be a fine tune when you work on it some more, which i hope you will
