Very sharp image. I like what you were going for here. I would've cropped it from the start of the building and gotten rid of as much of the lawn and trees on the left as possible. 6 from me.
Beautiful house and nice image - but the perspective here really doesn't shout out symmetry. There are many symmetric elements in the building but the off centered placement far from away the house does not show us really clearly. A close up of the arches and windows dead on would likely work a lot better.
