This is the image I've made for the "Spectacular" challenge.
The story:
"It is an another's planet. The Crater-City. This city has arisen from a fiery lava spouting out of the ground. Strange constructions of the city grow and develop in itself. But their functionality and forms are programmed by scientists. They feed on the fiery lava. Eventually they harden and take
unusual bionic shapes. People lodge here to use energy of a lava for own needs. And their children search for exciting and dangerous entertainments for themselves. They jump from a bubble to another and soar from depths of the city to its tops. They risk very much, they can fall in a fire-spitting
precipice at any moment. But force of danger and adventures is very great. And they do it again and again."
