Design project Theme board

When I thought about "theme board", what kind of feeling do I want in this project?, out of the blue, i imagined a handful of soil with a plant in the hand.
I had to question why I was thinking of this image, and why it will be appropriate. without the answer, I asked myself what else? I imagined a open ocean, or an image of an open field.
Once I found two photos that i wanted, it clicked in my head. I want a feeling of a strong foundation, and some feeling of freedom, grand, open, inspiring.
