I'd go back and shoot when the light is perfect. It looks a lovely setting and with the right quality of light I bet you could have a fantastic set of images. What direction are you facing - i.e. is sunrise or sunset a better time?
Not sure the corner itself is necessarily the most interesting composition though.
I think the concept is great and has lots of potential, just look at @kennysarmy image to see what I mean. Theres something just not right about this one though, even centring the column doesn't work because the ends are still not symmetrical. Definitely a go back and shoot again if its local.
