The easiest thing to do about the electrical box is to paint it the color of the house. It's low down, so it's not going to be noticed.

I'd stick to curved shapes for furniture (like you have) get cushions that match your door. It's hard to suggest plantings without knowing your zone, plus it looks like an early spring post, so when your shrubs leaf out, your garden will look far more lush.

It's a nice house and I really like the way the curved steps and path highlight your door. Doors in corners can be tough, but yours looks good.

I love those pots, thank you

Sigrid, thank you, I'll try that

Try putting a bench seating in front of the box; something with a low back that comes just to the glass of the window so it doesn't block the view. Then move your dinning set more to the right so the bush can give you a bit of privacy. Bring the turquoise of the door out with pillows for the bench and dinning set.

Chang out the picture for something that will stand out against the brick, not blend in with it. Consider large black house numbers vertically by the door.

I love the idea of potted plants on the patio. Use only one or two pots, you have such wonderful landscaping around the patio and house don't compete with it.

A few random thoughts. I like the idea of:

A lollipop container plant

A deep, steel-blue door

Blue in your patio furniture (brighter and lighter version of the door blue)

Where the X is, a nice big bit of garden statuary. There are such gorgeous things available. The reason I'd like it there is that it's nice when a curve in a path appears to be there to avoid something important -- a pond, a tree, whatever. In the same way that paths in the country wind around trees and stones and natural ponds. And something appealing there would be a welcome to anyone arriving.

A small point is that I think you should move your patio furniture more into the centre of that area -- it's a bit too close to the steps and the house. Take control of that space.
