First of all, thank you so much for participating in the challenge, Cassie! Your poem is amazing, so much emotion behind it.
I like how you incorporated the title of the painting into the title of your poem - very clever. :)
The painting is of a man who looks beaten down, very somber... the rain is falling down as he rows his boat in the cold, dreary swamp. You definitely captured the emotion in your poem that is portrayed in the picture.
You described the man watching the people who are studying him... seeing a world of rainbows, different colors surround them while his is nothing but gray. He knows that he cannot escape this misery, he is trapped within this frame. Yet, he has hope that the people who watch him will go out and live a colorful life, one that he has been denied.
"The canvas of your life awaits."
- I love your ending, that is truly beautiful and inspiring!
