Both of the images on this page were Challenge entries, when the subject was a U shape. In this one I linked them together and used Blade Pro to give them a pearly look. The sky was generated in Terragen and the angels are from angel tubes from tubz 4U.
In this image I wanted to give an impression of a mysterious source of power and light - an alien but not a hostile or evil one - something benign which glows with power like the sun and illuminates what it passes over. The landscape was generated in Terragen, and is fundamentally misty. I painted the light into the image with an almost transparent colour, building it up to be almost opaque in the centre of the stream of light, but not quite opaque enough to hide the waves in the water.
