OK, I'll have a go. Whenever we reduce something to a silhouette in a pic, it's best if it still creates a recognisable shape. This isn't some 'rule of photography', just an observation. For example, if a person's head is in silhouette, it really only works if seen from front (or back...) or, better still, in profile. A 'three-quarter' view won't make much 'visual sense'.
At first sight your pic looked like a ship, or a submarine, silhouetted against the sky. I looked again, and realised it was actually a stand in a stadium, surrounded by floodlights. The silhouette itself isn't too interesting, and the sunset is pretty low-key too. There's no real subject, and the pool of black in the foreground adds nothing to the pic. So I wasn't sure what it was about this particular scene that interested you.
