Hi Norm
Not sure what you are after but the ori pic looks pretty good. From here on in it is only personal preferences.
Having said this, I fiddled around with it as far as JPG would allow me. The only thing I would like to see is a little less washed out brightness in the cloud centere, in your last tweak it is still a bit much I think. I have reduced this a bit so it doesn't hit your eyes so much. Also I took a wee bit of the oversaturated yellow out which allows a bit of detail to come back and offers the eye a smoother coluor gradation. And since you don't quite like the flatness of your shot (I must agree) I have cranked up the texture of the beach in the foreground a bit also, which as a result pulled along the rest of the trees as well. The changes are pretty subtle, tell me what you think. But really, the whole thing is neither here nor there. (Good or bad, I can take it) Otherwise, nice shot, what are you complaining about.
Greetings
