Instant gratification, read you loud and clear.
The big plant looks good. Put it back.
Definitely a big tall painting, or a bigger mirror with a wood frame. That's the only thing in the corner without wood on it. The railing is fine, just contemporary looking. Paint color is okay, but all the other walls and trim are white so it makes it stand out. I like it with white trim,.. looks neat.
In the future, maybe you could make the staircase wider to fill that little space in if you don't like it.
DONT park the car there.
Just an idea. Happy Sunday! Hope you feel better.
