I was only able to get the first link to work. The second and third said that the track couldnt' be found and may have been removed.

Production sounds great in my headphones with the balance and aural spacing (I don't know if that is the term) of the instruments. I would bring the vocals up a touch in the mix.

The lead guitar at 3:00 sounded different but "cool." I wasn't to sure be your description what that was.
