Really dramatic silhouette, and well composed, Rob. A couple things worth mentioning.... It's worthwhile using a good Noise Reduction tool/program,even when you can't see any. ..and best to make that your first effort before any other editing. I expect that much of the noise (more easily discernable in the right side) is partially due to the posted image size, but when removed, there's considerably more separation in the puffy little clouds. Also, slightly darkening the sky area increases both drama and clarity in those huge blades.
