I like the emotional piano at the beginning, and how you experiment with pacing all throughout the intro. I love the light, airy vocals and progression. I think the vocals could be a little more up-front in the mix, though - the piano seemed to be edging out in front of them sometimes. This is a really well-structured and flowing piece, and the mix is clear overall. I think the instrumentation is a little simplistic, and some drums could really help give this piece more of a sense of drive, especially since the pacing of the lyrics is often rather quick. Overall, this is a beautiful piece, though. Keep up the good work, you two! :)
