Really struggling with this sunset photo

[Fotografer]

I've been working on this photo for the past hour and a half in lightroom, and I can't figure out what I still don't like about it. It just seems off to me, but I think I've been staring at it for so long that I don't realize what's wrong with it. I'm thinking maybe the sky could pop a little bit more? Not sure. Any suggestions?</p>
