You house has a lot going on already. I would not add more features. I'd paint the garage door to match the house, maybe paint the door a brighter color, and maybe paintnthe siding.

I would not add craftsman details to a decidedly not craftsman house, nor would I clutter up the facade with a second siding.

Frankly, I suspect your house will look plenty fresh on a sunny day in the spring with plants in bloom.
