Spectacular job! Very cinematic indeed!
At first I felt the last song a bit misplaced, but it was so grandious I had to give it another go and with the description I see it working! I did love the choirs and that they worked almost as a bridge for all the songs, but did sometimes feel that they played too much, what I mean is that their lack of presence in some parts would increase their impact on the part ahead, like in clash of the waterfall
Take care :)
