This is my rainbow concept, it's about how free nature is and how the human race used to be free to go anywhere they wanted to go, just like the rainbow. The rainbow is straightened out and the opposite colours are reflected in the puddle of water. This represents the fact that everything has changed for humans and how nothing is free anymore. We used to be a part of nature and hunted for our food and were happier than we are now.
I took a tree, in my imagination, and turned it upside down so that it represents a pair of lungs, as trees are the lungs of the World and help to keep us alive as they breathe oxygen into our atmosphere, which is free. I made the leaves of the tree huge, to point out the fact that it's the leaves that provide the oxygen.
This is a charcoal drawing of a female life model as she is free of clothes just as our ancestors were in the beginning. They got vitamin d from the sun as they were naked and so didn't get multiple sclorocies.
