Christmas Cookie Shop and would love input
Having the rounded windows as the corners is an idea you should definitely keep. Having the rounded pieces on the roof continues that rounded pattern. I would also like to see rounded edges directly above the windows too.
I agree with Tim’s idea. Of course one thing that brings customers into a bakery is seeing the baked goods in the window. Also you might want to consider the overall color scheme could be like a baked good itself; consider separating the white parts from each other with a warm color, so the white parts look more like icing.
