Although only one layer, there is a dark shadow in the right lower part of this winter-like motive This is not a result of any filter or post processing, this being a raw fractal In fact the shadow is a natural part of the mathematical terrain

Ultra Fractal, formula Cubic Parameterspace3 in the sp3-module written by my dear friend Stig Pettersson, Greenseng here at DeviantART. All his modules, as well as mine can be downloaded from [link]

More info about Cubics can be found at my Cubic Tutorial [link] and the "cubic" articles in my Chaotic series [link]

Below the parameter file. Play and have fun :
