The overall mix is a bit bass-heavy. I think you need to work with the vocal levels a bit - they sound about right in the really stripped down sections at the beginning and in the middle, but they seem to get quieter when other sounds start coming in. Also that reverbed sound that starts at 1:52 didn't sound quite right when I listened.
One of the notes in your bassline (1:08 is the first one) *might* need changing - I can't decide if it works or not. At 3:16 with that guitar it's creating some pretty complex harmonics (I think that's the right word) that maybe don't fit the song. I'd get some other opinions on this though, it's partly just personal taste.
I do actually like this btw, even if it doesn't sound like it from the above
