I tackled this part first as it was obviously the crucial part of the movie. It's very difficult to balance the line between a haunting sentimentality and awful-dripping-with-sugar corny crap. So after a few attempts I trimmed it down just to a few instruments, kept it really simple and did my best not to make the music the feature. Just enough to supply the emotional input needed for the ears to hear what the eyes are seeing.
