First off, welcome to the LE rabbit hole...Since you asked, you have a good scene for LE, so that is working in your favor. It looks like a really nice spot that you could work several images and enjoy some time there.
For me, the exposure was too long, the surf is blown out completely, and it has no detail. It can be tricky to get the right balance between exposing the foreground and the surf, practice will tell you what the surf will do when you are watching it before making an LE exposure. Its weird, I "see" in LE now...my mind can visualize what water and surf will render like in LE...it was not like that when I first started out.
The sky is also fairly featureless, sometimes that works, sometimes not as much. When I have a featureless sky that doesn't work in LE as much, I will focus more on the rocks and surf, ignoring the sky, maybe only include a little of it above the horizon. There is some weird banding going on in the sky too. Not sure if it is more from processing or something native to the exposure.
