The circle of calmness

I saw the common design in some internet pictures. And I've restudy it and put my ideas, create whole new composition. I try to include the triangle of three elements: nature, space and fire.
At first i create full 3d environment using displacement maps and volumetric objects. And then I've rendered it and past the result into background image, so it's completely integrated into the composition.
In my feeling this is very cool place to meditate.
