Great shot but I agree with the comments about the too-central placing of the stump. However, I would crop away the bottom half of the relatively boring area of the sand below the stump. That would place the roots of the stump in a more prominent position.
Another option would be to shoot with the camera lower and closer to focus attention on the roots, which I consider to be more interesting than the trunk. Although you would focus on the roots, when you take the photo, you would compose it so the roots were in the lower half of the frame and to the left so you include some, if not all, of the trunk.
Then, you might be concerned that the shot did not include enough of the wave action. Then, you would have to decide if your image was about the stump roots or about the waves.
My recommendations above are for where the stump is the subject. If you want a picture which focuses on the waves, I would not include such a dominant second subject, such as, this stump or, if I did, I would make it less dominant by only including the left of it (that is, moving it to the right edge of the frame).
