Pretty cool concept and shot. Compositionally I wouldn't change a thing placement of everything is spot on. I'd suggest a couple things though: 1) trying to recover the blown-out area; 2) correct the very-slight tilt; and 3) try a B&W conversion.
It's not crooked really, the horizon is just slightly distorted. And I tried but I couldn't get any more detail out of the highlights. It was ridiculously bright, had a 10 stop ND just to get my shutter low enough for the effect I wanted.
