I would move that backlight away. The nice perspective lines you have going with the pillars are broken up too much by the trees. Try something else with the trees, like putting them behind the pillars? Also, the statue seems to be the focal point of the composition (at least it seems that way to me), but it's not detailed enough for that. Could you perhaps move it closer to the camera? Overall, I like the idea, but you're right, it's not quite there yet.
