If your siding is, as it appears, gray, consider a muted cobalt blue for your front door, leaving the frame match your window frames and adding a brass kick plate for a more finished look..

Like the picture window. Have you considered hanging a stained glass panel there?

pretty house! I love both previous comments (wood door, or the blue). I would love to see more of that house so could your trim those hedges?? lol. jk.

A flower pot with some shade loving pretty flowers would look nice too. (Impatiens or Begonias in a ceramic pot or even in a hanging pot in front of the wider brick area, just for a little bit of color.
