Hi Igor.
I really like your Image and the Structures in it. The colours are beautiful and I would definitely keep the leaf inside. Though I would crop it slightly different, as the leaf is far up in the frame. Maybe you could try a version where you reduce the lower 1/4 th and also 1/4 th of the left side. So zoom in to the upper right. In my oppinion the two main parts of the image are the rock and the leaf. The lines are additional beautiful elements.
The leaf is not meant to be a main focus point. It’s supposed to be a mystery with the leaf being a touch of reality. Your comment makes it more convincing that the leaf does not belong at all in this image. Not the way I envisioned it at least.
