(Ps apart from the crappy angle on the jetty , why does this shot seem so wrong, is it too much jetty or what ?)
This is a non critique section, so I am just offering suggestions since you ask.
Its been done time and time again, but looking dead centre down a jetty just works.
Perhaps you don't need the wide part of the jetty at all, what sets the picture apart is the storm cloud so you just have the jetty pointing to it.
At the foot of that slop might like interesting and different, or the usual further forward looking down a flat jetty.
Just try different things and pick your favourite is the best suggestion I can offer.
