I think the intro might be a little too busy. You would probably be better off just starting it at the 10 or 18 second mark. It's a really cool lead line, rhthymicly. I like how you dropped out the melody when they lyrics started, it made it a lot easier to hear (and pay attention) the vocals.
I like the idea of adding orchestral elements at the 2:42 mark, but I think there should be more. Maybe some horns or a timpani or something. The pizzicato strings sound slightly out of place by themselves, but if there was more accompanying it (during 2:40+) it might not be so jarring.
The vocal harmony at the end was neat, but you waited too long to bring it in. I would drop it all together and end on a quick "got me good" use the harmony on that line earlier.
Anyways, this is a good song with a lot of potential. I hope you take my words with a grain of salt., I'm just trying to help out (saw this on the WIP thread)
