Not sure about the rotated orientation. got to love the CA. You might be able to desat the blue to minimize it, there doesn't seem to be much else that is blue in this shot.
Good subject, and composed in an interesting manner. Appears to be some exposure problems though. The sky is really blown out, and there is some serious chromatic abbhorations along all the contrasting edges of wood and sky. Perhaps a different time of day would produce stronger results? Or maybe even under exposing with some fill flash.
cool tecturesand colors in the wood and the shadows to the right add some depth to it, the overexposed sky behind bothers me a little though, good luck
