Missin' a lil' sumthin'. = P
First off, great job with this song. Pardon me for pooping on people, but I rarely ever find a Newgrounds song with such standards as this, and it's a relief to find one. Well done.
However, I still reserve my right to nitpick. Something is missing. My first instinct tells me that you need a more definite pad in the middle frequencies. I hear the piano and strings, which are nice, but they're too rhythmic to qualify as a pad.
Again, this doesn't mean that the song is bad in any form or fashion. But it's these small differences that raise the bar.
