I agree with David, gorgeous capture Mike. My only comment would be on the whites. The usual nit in the whites area are that they are blown, in this case I think they appear a little "dirty" and could possible go a bit brighter. This would also add a bit more contrast to the image.
Beautiful image, Mike. As for the whites, I'm not sure if they look grayish or if it is a very slight color cast. If it were possible to get them white without overexposing it might make the image even better.
