What is left of the garage?

Is that a porch and front entrance -- being able to see that might help.

You might consider adding a gable roof or at least half gable roof to that left ground floor part of the house.

Adding something in front of the "blank wall" could also help -- a landscaping feature ... or is this adjacent to a sidewalk or small parking space that would prevent that?

Small gables and/or upscale window awnings and/or shutters or pergolas for the small windows on the left side of the building on the second and third floor might help.
