Yes, along those lines, Dave, though I'd say more of the same. To me the scene is all about the tortured foreground, which offers a bit of a lead-in, and the gentle fells in the distance. The sky is interesting, but secondary? Maybe lose the very near foreground, so we go straight into those lines (more local contrast or clarity), burn in the sky from the top right to push the eye back down, and perhaps lighten the fells (or whatever they're called!) but only a touch. Dark and foreboding....
