I love how singing is such a theme here; very beautiful!
It was difficult to picture the characters, though. I know brevity was part of the challenge but a few more words of description would have been nice. Also, the transition where they beginning walking to the temple felt very abrupt, and I was left wondering what Xochitl was thinking about the silence during there walk!
Overall, I loved the glimpses of the culture in your use of names. There were some beautiful passages!
