You could use a bit more landscaping, and one, at least, small flowering tree in the front yard, for interest. I had to look very hard to see your chairs on the porch. They need to be brighter, or at least have some nice bright cushions on them. Your paint is fine. It just needs personality. Remove those green balls of shrubs, and put some pretty perennials in there, both green, and flowering type.

Plain? Not at all. It’s lovely.

Your home is beautiful and the person who maintains your lawn is a rockstar. Cat_ky's suggestions to add color may be just what you need.

Your house is really nice. It's not plain. Frankly, it looks like lots of other people's inspo pics or their proud "after" of a before and after. If you're putting it on the market, don't take the pic from the driveway.
