When looking at this scene, you need to see what is/are the dominant element(s). These appear to be the many horizontal shadow lines. So the method to highlight them would be either to reinforce their regularity, or to provide a contrast. What breaks the regularity are the two fronds center left, and the rather bright stalk of bamboo running across the horizontal center of the image.
A contrast to the horizontal shadows, could have been the vertical stalks which we see in the upper part of the picture, but the way you have framed the image, we dont get much sense of contrast.
Another effective technique is to put lines on a diagonal, at an angle that signals that you really mean it. In the current image, the horizontal lines are on a weak diagonal, and this creates some doubt in the viewers mind as to whether this was an accidental choice or deliberate.
Your choice of using monochrome is a good method for reinforcing pattern and texture, but in this case, the texture of the forest floor overwhelms the pattern of the shadows, and is not interesting enough in its own right. This leads to the image looking cluttered.
