It doesn't sound right (the music is fine, I'm talking about the overall recording), it lacks sparkle and sounds a bit dull, like someone took the shine off of it. At least that's the impression I get right off the bat. I turned it up but that didn't help it any. I did notice that as I listened my ears adjusted a little and the "dull" sound became a little less obtrusive, but only a little. Try making a few small EQ adjustments and see if that helps it out.
Any other thoughts? Time for mastering soon...
