Honestly, I love the exterior as is. I like the natural stone, paint that looks fresh and is a great color, the wood front door and the red accent chairs.

Cute place.

I like your natural wood door but it looks dwarfed by the gable above it. When you paint the trim to match the windows I think it will help.

I would keep the fascia the taupe colour it currently is. It blends nicely with the roof. I would consider bringing that colour onto the gable too, to help the gable fade back a bit.

Whatever you choose should be decided after you whitewash. All the colours are nicely coordinated with the stone and everything will change once it's painted.

The front door color is too warm for the stone. It should be more of a neutral brown. The red accent chairs should be a neutral color.

Hard to see your landscaping but the beds seem to be quite narrow, and have few evergreens. I'd beef them up. Or maybe they're just planted and small?

Otherwise I wouldn't change anything.
