This is a great example of thinking outside of the box, and the great number of possibilities you have with stucco. I had always wondered what it would look like to have rounded corners, and not have the cornice moulding contour it. It is definitely the first project I have seen to do this, and was done successfully! On top of that, this was a retrofit, and the old wall actually had squared corner.
It needs just a few more mouldings over top of the store-front windows and the windows on the second level to further reinforce the horizontal direction that the eye naturally takes, traveling from one end, over each protruding entrance, to the far side.
Very well done!
