Oh, yes, a sunset. :-) There are too much blacks without details, and it's hard to find our what's this - anyway, sharp - silhouette exactly without the title. I can't see the implementation of the challenge, where is old and new on this photo?
The picture is a aesthetically pleasing to me. I infer that the new/old contrast was the newish carrier with the eternity of nature (the water, the sun)? I think the sunset confuses it a little bit, because then I start to think of the day as old, but obviously this "day" is newer than the carrier. (The fact that this photo makes me think about what is new and what is old is a good sign though.)
