pollyannagal I would not bring the brick further down the sides as it would be too heavy for the size of the windows. It is good as it is. I'm assuming that the stucco will be on the inner portion of the arch?
American Marine Systems In Italy, stone and brick was used together. Brick was used where closer tolerances were needed, like a window, a door frame. even though your home looks more formal, check out a book called Italian Rustic by E. Minchilli, there is a section on windows, but throughout the book, you'll see how brick was used.
pmorganii Ok...so my gut was telling me no on this...so I'm pulling it off, and doing a decorative arch in limestone. Finishing with dark stained shutters. I'll load a finish pic when done. THANKS FOR ALL THE FEEDBACK!!
victorianbungalowranch I think it looks unbalanced because the brickwork extends too far down and the hood bracket should be stucco or limestone. Also the brick may be a bit wide for the window and the sill not heavy and wide enough. The workmanship looks very good though. If you look at old buildings you can see how they did it.
Stucco color is a light grey brown

Of course going with limestone is classic.
