Looking at your photo, I see an interesting shape. Foreground/background dynamics are interesting. I'm a blue fan, so the colors resonate with me. I can see this as a background image in an advertisement.
But it doesn't hold my interest, and is less interesting than other subjects in the challenge. It is one thing to master your camera and the post processing and another to take photos that engage your audience. You have very good performance on the former, but could work on the latter.
