Add a live plant for greenery, a mother in laws tongue potted plant is great indoors and doesn't require a lot of light, they will grow straight upwards and about 3' to 4' in height.

A rug is a must. I agree that a bench and new light fixture would be nice also. Post pictures when you update your look.

Just removing the textures on the walls would make a huge impact !

Thank you for all the comments.

I had long Bamboo shoots(4 feet) where I have kept the vase.

Any thoughts on colours for the walls and the door.

A bench and a light fixture is a good idea. I will post new pictures when done.

The main distraction is the floor.
Replace the floor tiles with something less stark.

A bench or chair in front of the railing. Long runner from door to bench. Repaint and add a new light fixture.

Remove the texture from the wall, change the light fixture, and consider painting the stair railing (black), this will really update the space and give you a nice palette. There is too much of the same tone and it is very conservative feeling. Add drama with a piece or two of statement furniture like a bench, chair, art that reflects you. You can find a lot of fun inexpensive pieces at places like Home Goods where you can have fun and experiment (every few years even!). Keep it simple but have fun.
I would keep the door the same color as the wall to keep the space feeling larger than it is.
