I shortened the height of the fire so that it looked more like a flame burning in the cauldron and less like a wispy pillar of flames floating up out of it. I also added a directional light and extended its radius to 180 degrees. By placing it within the area of the flames, it appears as if the fire is lighting the temple.
I also added a statute that I created using a cylinder for the body and a sphere for the head, then shaping it using CV points. The statue uses a modified Rock texture.
