Here Is my Interpretation of art challenge.
All the fishes were staying at the bottom of the sea or atleast deep down where they feel safe enough that nobody could harm them. They discourage all other fishes to go near the surface, to stay deep down where they all are staying if they want to live, otherwise they will be caught by fisherman and would be eaten or even worse, they would be kept alive to be showcased in aquarium.
Due to this all of the fishes were afraid to go near the surface and no one would even think about seeing what's above it. But One day a whale wanted to know what is above the surface, she doesn't want to spend her life in shackles and boundaries, she was afraid of being living under the fear for her whole life.
So then she decided, she would rise and rise, it was very difficult for her. She even thought of quitting her idea, she thought of turning back, everybody down there was calling her to come back, to return to where it was so called safe. But again she remembered why she wanted to do it and she started swimming to the surface where there would be a different world, the world only she has imagined.
Everybody else thought she had made a mistake and she has ruined her life, some were making fun of her, some were feeling sorry for her but nobody trusted her. At the end she reached up there, she was mesmerized to see the sun, the mountains, the clouds, the air.
She was proud that she has seen something nobody else could ever have imagined. All the other fishes were praising her now, they started believing in her and respecting her. Then the whale jumped in the sky in joy of her success, into the clouds,
Suddenly satans rise from the hell and started taking the sea to the hell. All the fishes die, and we can see their bodies in the pic, but only one whale remains which was above their reach.
And this is the story of Human life. Every time some one tries to do something innovative, something far better for this world, people will scare you by telling to do the normal things, to do your normal jobs otherwise you will ruin your life, but those who follow their dreams, those who follow their curiosities fly above the sea and leave their name, their legacy in history. All the other normal fishes will be wept out in history and nobody will remember them.
