Although the door goes with the paint & roof colors, it doesn't add any contrast or pizzazz.

You might try a deep green or deep lacquer red.

It looks like you have lots of space for a cottage garden or rose garden;

greenery & flowers will help to make the house look more "finished".

The issue isn't the door color - there is a lot of contrast between the door and the rest of the house. Before you go changing the color of the door - assuming you like the color - I would try dressing up the outside foyer area. A nice, big indoor-outdoor mat, some large pots on the sides of the door, maybe a bench, etc.
