What are your plans with the brick? Does the new roof color go with the brick? I would not install the "Tudor" trim boards were it me. The facade is on the smaller side and would be to busy IMHO. What are your plans for the windows, are they getting painted as well?

There's a house in a similar style near me, the stucco has a gray, rather than a yellow undertone, and they have dark purple/gray shutters and trim. It looks fabulous. Interesting without being crazy. Unique.

You could do a bright, sunny yellow for your shutters (Sw cheerful, maybe?), a light coral or a pale, limey green (Gleeful?).

I, too, would not add any Tudor trim elements.
