I (think) I can see what you were trying to achieve here, but there is just too much space devoid of any real interest for my taste... In my opinion the image would be stronger if you were to lift the detail in the surrounding bush somewhat. Having said that, it looks to have been a majestic sight...
If you try lifting detail until it is just visible and tighten the crop up using a ROTs placement of the tree on the left vertical grid, I feel this will strengthen the image.
