That's a very good song and the mix of old and new tracks feels seamless. I felt an overall lack of high end in the frequency balance, and in particular I wanted more presence in the snare and sparkle in the cymbals, high-mids and highs respectively. Maybe aptly an exciter to the overall mix? The mix sounds balanced and I love the guitar tones, especially the texture of the rhythm, though a couple times they seemed to get a little lost in the piano, bass, keys bed. The vocal sound really strong and I particularly like the sound in the bridge. Good job, if you hadn't mentioned I would not have guessed the guitar and vocal were 10 years old.
