Not bad at all, but I'm not sure I like the sky being darker toward the center. That has occasionally happened to me when I've used a CP filter on a very wide angle lens, like wider than 18mm APS/27mm FF.
I like the photo, but the HDR looks a little overdone for my taste. Like others have said the dark sky in the center looks off, but it easily fixed, and the horizon line being slightly crooked bothers me.
I did a REALLY quick edit in photoshop. You can see where I did some dodging in the sky and it doesn't look great, but with the original file you could make it look better.
