"Forest Cathedral" an abstract painting by South African artist Marie Theron

Is it possible to paint an entirely non-representational work of art? Even the most abstract work is usually abstracted from nature, or maybe from ideas and emotions...there is something there. And like the eye that is forced to look upon a dirt wall, we start seeing some images. I remember in my knotty pine bedroom ceiling there was a little pigmy complete with  a sword that probably only I could see. Even Leonardo da Vinci recommended that artists do that. This is a quote from a Tate Gallery article called "The deliberate accident in art"

Ever since Leonardo da Vinci urged artists to search for inspiration in the dirt on walls or the streaked patterns in stones, they have found that the accidental blot, the chance mark, or the naturally occurring stain can be a starting point for some extraordinary art.

I have decided to do more paintings in the  same style as "Forest Rain". I once again started with an organic shape. You can see the tree-like image in the right side of the painting. I then created a dark green forest floor to lead the eye into the painting. Harmonizing and contrasting colours were placed and I followed a square grid to bring an order of an architectural nature into the work. Do you agree with me that the theme; "Forest Cathedral" is suitable?
