There is a lot of unique activity at play in this image. First, the defined geometric shapes in the flagstone and in the telescope stand yield their corners to the soft-edged stones of the wall. Beyond that, moving vertically up the image, shapes become quite ambiguous and tightly blended together in the treetops. Continuing up the image, those shapes blend into an abyss and and then almost seem to erupt in larger form back out in the form of clouds.
Additionally, there is a strong yellow floor to the image and a cool blue ceiling. Bring yellow and blue together and you get green - exactly what exists in the middle-thirds of the image.
This is image is a visual journey in color, form and space.
I like the composition of the frame and the idea behind it, but it feels like IMO, that you went a bit far with the processing. Your lightest area is in the foreground and kind of traps your eye to the forward section especially as it is very dark in the background. HTH.
