I like banal subjects. I'm feeling like the window is supposed to frame a subject. To me the reflection of the house can not compete with the window it self.
I like the pink flower :) The windows are reflecting well, and their smoothness contrasts nicely with the rocky wall. I'm not crazy about the shingly roof pieces. Next time, you might consider 'planting' a reflection of something interesting in the window, and brightening the whole pic by using levels and/or curves. Just some thoughts ;-)
