Compositionally, I like the balance between the sun and the boat silhouette. I also like the "almost" parallel between the pier and the waterline. It does feel a touch "off" though. I'm wondering if a horizontal crop/composition would make it a bit more stable.
Technically, there seems to be just a little artifacting, which could be caused from adjusting colors, etc. in post processing. I really like the warm pink colors -- it truly conveys a sense of evening and warmth. Likewise, the fact that it is not a true silhouette helps the shot, I think.
Overall, well done, and congratulations on your personal best. I do hope this is the beginning of a trend for you!
