Looks good! It's always tricky trying to adapt to bay windows. I think the vertical boards look good, it better sells the storm shutters visual from the street on the 3 window bay. You can play around and see if you can 'combine' the 4 windows into 2 boarded up windows with slightly thicker foam boards on the outer edges to flatten out the plane. I haven't had great success doing it since the wife likes her natural light so we compromise with hanging heads inside along with some red gel hand prints. The 4 window bay would also be great for projection as well where the 3 bay has a lot of cross trim that would interfere with the effect.
