There is a very obvious line at the face of the statue that divides the face from the background. Honestly, I've never seen any such feature element in real life that photography is supposed to capture. Yes, I've seen it in the rather mindlessly fun of painting by the numbers. There you paint up to the line borders of various areas. Seems to me that when a capture is produced that includes such a feature that testifies to the photographer's lack of skill. So, I would guess from your capture that you are still in a learning stage in this form of your art. Overall, I like the composition and subject matter. But, the details need work.
