>>10097236This is just a spitball sketch so some things might not be possible or look much better in reality.
-Rose window might be too much like you're saying, and with a big one you're losing the nice dormer windows. If you shrink the dormers into faux windows and put them higher up you might be able to keep them and have more room to play with for a central feature. In my mind's eye a ribbon of nougat on the bottom edge of the roof would look good against a railing so I sketched it quickly, but it might not actually improve anything in reality. It depends on where the roof would end based on what you put in this area.
-In architecture generally the heavier-looking elements are lowest in order to imply strength, so while the gray pilasters on the second floor look awesome they might look even better on the base floor. You might be able to preserve the original skinny supports on the base floor by building out an awning. The increased height you plan on adding to the base floor will also improve the general look a lot.
-I split the windows on the second floor to make an excuse to use the gray fender pieces that come in the set. They might not work with your current pilaster setup, and the current big window does look sweet, but some division might generate more visual engagement and incorporate more nougat into the facade when displayed with your other modulars.
Again just spitballing - consider all or none of it. I think regardless what you have is really good and with a few more iterations you'll have something much more feature-rich to be proud of.
