I think your house is very nice
reminiscent of a French country house
Depending on the budget you could add a large porch with a portico as seen in this wee pic :-)

It's a bit hard to see the door, but a bold door and the trim painted darker but still a warm color. Finish it off with large planters on either side (perhaps a bright rich color) of the door with some Architectural and/or interesting plants. I think would do a lot without costing too much

I just saw the comment that the windows are vinyl. I agree painting lighter to get them to blend is the way to go

Is that a real antenna? I haven't seen one of those in decades!

You could add larger lights. A fancy pediment will look more colonial, won't it? The rustic brick looks more farmhouse than colonial to me.

I like the look of "no shutters" on your house.

If possible, I would re-paint the white around the windows ---changing it to a neutral light-beige color (the goal being NOT to highlight the "around the window" lines)…

OR, you could go in the other direction and re-paint all that white the dark brown and highlight the windows (although I personally prefer non-highlighting approach for your house)..

Either way, I don't think white is as good of a look as either light-beige or dark brown would be.

And, yes, I think a covered entrance would be the right touch, both for function and appearance. I picture something about the width from light fixture to light fixture. I think that would be a good scale for your house.

I don't agree with the idea of adding a full-width porch----I think that would be too much. The photo above looks like it has more room between first and second floors (taller than 8 foot ceilings) than your house has. I think a full porch would overwhelm the front of your house and spoil its simple, classic (and appealing) lines… (Just my opinion)

Nice bones to your house. Nice brick color. I don't think much is necessary to give it the "right look."

unfortunately, our windows are vinyl. I agree that they would have looked better in a light beige color. However, the previous onwers put these in so we are stuck with them. I also hate that they stand out. Can you paint a vinyl window? It might void the warranty :(

and yes, we have a real, 1970's antenna on top. It's on our list of things to go, clearly.

I could be off here, but what I see is that the pitch of the roof is too low. With that said I do realize the pain it would be to rip it completely off and add a steeper pitched roof, but it would look more French Country if you could! :o) The main floor windows with the trim above them and the door painted red looks great, so does the color of the bricks! Alas, its the roof! :o(

I had commented on your original post when you had the shutters up - so saw this follow up to that. I do think that you could use something else so that it doesn't look so bare, particularly without shutters. I would add bushes with height, in between the windows on the garage. I would add large planters on either side of the front door to fill in that space. And I would increase the size of the lights to either side. I think the door would look better in a lighter color, perhaps even something like the blue shown in mick50's photo. Your house has more of a Georgian facade and that might be somewhere to look in terms of a possible pediment for over the door. Here's some examples of Georgian houses, many with pediments:
