awesome. Done in a spirit of exploration, I couldn't help but add a little light bloom: the sky back there is so bright
and overexposed, the light would bleed into the darks. This can be simulated fairly convincingly by pulling a luminance mask, doing an "in" with the image in that mask,
then blurring that, than doing an "out" of that result and overing or screening it back on. If you blur too much, you start wrecking the scale. What really helps seal the deal,
if you have it available, is to mult the result of the previous procedure by a facing ratio render of your object, so that surfaces that are facing camera "block" more light bleeding, and surfaces that are approaching parallel to camera let more light bleed through. This was just a 1 minute quickie in photoshop, as I don't have a compositing package at home... fwiw...
