When was the pic taken? Why are your hydrangeas yellow? Because it was fall? How do they look today? I find the yews to be not very inspired. I'd probably remove them. I'd flank your door evergreen azaleas with a bloom. I'd put a large shrub or small tree where the rightmost yew is.

I'd move the yews to the corners of your lot. Ditto the hydrangeas replaced by the azaleas. I'd put a small, pretty tree in your front yard.

I would not have noticed the stone in the gable. On the whole, I'd vote for replacement with siding, but I don't think it will make a big difference.

I tried to study your house’s facade up close. Is that real stone or artificial? It almost looks too uniform to be real. If it’s not, I’d take it off and mount siding to match the rest of the house. And remove the scallops.

Yes, the landscape needs work. Especially that big evergreen under the window. And, yeah, why are the hydrangeas yellow?

Shorter shrubs or plants under windows, Pull some of the landscaping forward a bit. Great color choice on the front door—- wish the storm door could match.

As already asked, why do the shrubs look so dismal? Replace with small evergreens or perennials that die to the ground in winter. Stone work looks fine but get rid of the blue door. Out of keeping with the rest of a nice looking house Maybe a dark green.

Some visual

Don't remove the scallops. They're an attractive decoration. So many people argue you should strip any ornamentation if it's not today's trendy ornamentation. They result is making house bland and boring. I also think the blue door goes well with the stone, but not the siding in back, so, I'd vote for green, too.

Here are the scallops. They seem so mismatched with the stone. To me anyway.

"As already asked, why do the shrubs look so dismal?"

If the photo was taken in late summer/autumn that is just what Hydrangeas can look like at that time. The foliage will drop soon and the blooms will dry out. It doesn't mean there's anything wrong with them.

"Landscaping or siding?" How about both?

I agree that the stone doesn't belong on the unsupported overhang. If budget permits, I'd remove it and replace with shakes stained the same color as the siding, for a textural but not a color difference. Presumably replacing the thicker stone with thinner shakes will make space for trim boards to fit under the roof edge.

This is perhaps more landscaping than you had in mind, but I had fun playing! I lowered the evergreens, kept the hydrangeas, contained behind low stone-faced walls for structure when the hydrangeas are bare, planted an evergreen ground cover around the walls. (Note that the walls are not right next to the driveways, for more forgiving driving!) I'd plant bulbs in the ground cover for spring interest before the hydrangeas get going. This small tree is a crape myrtle; you might need to substitute something else if you're in a colder climate. I kept some grass, but it looks like it's struggling currently (drought? shade?), so you might need an alternative.

Cute house! Reminds me of a houseboat, for some reason. :)

Sweet home. It reminds me of a stone storybook cottage in the woods. If it were mine, I’d play up the window at the top front with shutters and a scalloped window box. I’d add larger front light and mailbox. Then straight out from the large window in the front yard I’d put a circular bed of an ornamental tree that flowers in spring, with some hostas, and daylillies under it. I’d take out the big evergreens and plant small holly shrubs and mums. I would put dark mulch to ground them.
