You might post this on home decorating forum. I can tell you they will dislike your shutters (too narrow) . . . it is sort of a "thing" there that crops up often - the idea that the shutters should "look" like they could close and cover the window.

Not sure what family of colors you're into for trim (blues, greens, etc) but I've been looking at Homburg Gray (Sherwin Williams) for updating my shutters & exterior doors. I bought a sample planning for a bedroom and though it didn't work there I know I'll find some way I'll incorporate this gorgeous deep deep bluish green into my home color sceme.

Right now you have 5 colors, roof, trim, shutters, brick and walls. Go with browns and beiges if you like a monocromatic kind of look. If not, kick it up with a grey and a green. What you pick will be against the brown brick. Good luck

This is what we ended up with - I'm happy with it, but wish it was a warmer gray, or that there was a little more contrast somewhere - just not sure how to incorporate that

The front door looks like it could be kicked up a notch

Do you mean a darker coral? Like a Poppy/red color?

Yeah maybe red. It just seems to be competing with the red brick. It sort of gets lost....

Maybe just a different less match my color. Just my take though

WOW after pics looks fabulous!!! Love the color you went with! And the windows really "pop" with the shutters removed.
