Hey man, I really like the song. Sounds nicely mixed and has a nice tone all around. One thing you might play with is the panning of the vocals, especially when the harmonized parts come around. For example, you could record two tracks of harmony and spread them to the left and right channels when you want and bring them back to the center when you want. Also, ever thought of having that "I guess I really" part be a sort of call and answer between the left and right channels? You can have it start at the left and bounce to the right and go back and forth until things eventually settle in the middle. Just my two cents...
