Very well done - not too clinical and not overly metaphysical. I don't understand why they used such bright, cold white illumination. Perhaps it is best for analytical purposes, but it would have been much more in line with the spirit of the production if they had used lighting of a temperature mimicking what the early people would have used (like firelight). This would have given the audience a better aesthetic impression of what the images looked like to the artists and their contemporary brethren.
