This middle section contained a beat of Tala climbing into a canoe and reflecting on her lost dream of voyaging with her people. My guess is, that this was skewing the scene too much toward Tala and away from Moana. Too many agendas in a single sequence can sometimes muddy the waters. It was eventually decided to leave Tala outside the cave, insuring that the following beat would be Moana's moment alone.
This last image was a screen cap from a colleague who was modeling the cave environment at the time. We got together and talked about the sequence and camera placement, after which he was able to give me a number of screen caps that I was able to use.
