I like classic farmhouses, too, such as the reproduction above. But once you have half the structure sort of symmetrical and the other not you've got something else entirely. Adding porches and dormers won't help.

What about a porch from front door all the way over to right side of house. Add a porch swing too!

Worth - thanks for the link to Connor home. Lots of good ideas there.

Peytonrod - good suggestions. Will try that.

There are several mistakes from a historical perspective:
The house is intended to look like it grew in stages, the right side should appear distinct from the main bloc of the structure. So the siding and roof lines should not run through; it would be best if the roofline of the rt. part broke from the main roof and the main bloc stood forward or back from the wing.
The upper windows would look better if they were 9/6 instead of just smaller 9/9's.
The windows of the "addition" could all be made distinct from those of the main bloc.
The portico is improperly detailed. The columns should be out at the very edge of the beam line, not inset from them by inches; that is making the portico top-heavy.
I don't care for the casement windows above the portico. An oval window (or pair of them) a circular window, or a single 6/6 would be preferable. What's in the space behind?
Window apron molding on a "Federal" exterior has no precedent and looks ridiculous, unless rendered in stone masonry.

What about continuing the garage bump all the way up and getting a bit more space on the second floor as well? I wouldn't do it as a hip either A gable would look more at home. Then instead of the oddly proportioned portico, do a porch across the front that is equal in size to the bump of the garage. That will take it into a more farmhouse looking direction, but the main body of the home will still have the clean lines that appeal to you, yet hopefully that will add enough change in facade plane to be "interesting" to your wife.

This feedback is great. Will go back to the "drawing board" and come back with something different.

I was going to say essentially the same things as Casey but then it occurred to me that a possible approach would be the more flexible Colonial Revival style. Then the facade could be asymmetrical with paired windows (not found on Colonial houses). To me narrow paired windows are a hold over from the Victorian era or a cheap looking attempt to add style (that is actually expensive) and should either be more generous in width or a very wide single window.

But the sills should definitely not be "trimmed"; they should have thick "historical" profile sub-sills so the jamb trim can rest on it as linked below.

Does the grade really have to drop off so fast and leave the portico hanging in the air?

I don't know what to tell you about the garage but I would not want to go farther with design advice without seeing all of the drawings.

About as classic a New England farmhouse as you can get. I guess they didn't see the memo about the windows. (I wish though they had opted for an undergound hydro connection!)

unsure of your actual floorplan , or desires ...
just a tweak ...

Summerfield - what an amazing difference. The separation of the right side of the house, as others suggested, makes a huge difference. Thanks so much for the inspiration!!!

Worthy, dude, that's not Federal, which it what the OP's trying M/L to be. That's a true post & beam center-chimney NE saltbox of the period. Not a wannabe.
