I think the window would like shutters (must be large enough to look like they could function)
and a window box the length of the window. I would have the shutters match the gable and trim.

Agree with felizlady's suggestions. Plus, consider replacing the current siding on the gable with shake.

I would advise new siding in both gables. Check out James Hardie siding. No shutters; window seems a poor style to carry them off.

Shutters and a window box to give the wall some dimension. Change or paint the siding in the gable—white is a very strong contrast to the dark brick. Eventually change the color of the gutters to a darker color, too, then the white windows will be the accent color.

I like Feliz's suggestion - plus, I would re-do the landscaping to include some taller plantings in the back to marry the window box and the landscaping. That will bring your eyes down and the gable will appear grounded.

The white is a bit stark and makes the brick look drabber...after adding elements suggested ...to lessen the impression of all the dark brick...a pale color will warm up the curb appeal...the most popular color in these situations is usually sage green

A strip of wide trim across the bottom of the gable will also add a “more finished” look..

I think wht you have is ' stunning " . Deserves an unequidistant row of three Italian Spikey 6' Cypress 10 ' in foreground from gable side.

It's fine. Houses are not meant to have details on every square inch. Most of the time, adding "interest" is cluttering a simple, but elegant facade.

Google “gable decoration”. There may be an idea there which could accommodate the vent.
