Hello.
i am needing some advice on some wallpaper choice on below locations.
1) Entrance hallway - 9 meter long. 9 feet ceiling 1.5 meter wide
2) An study room / home office wall
3) A staircase that has a large window in it.

For the study room i am wanting something thats natural but gives an office vibe.

For the staircase, I am wanting something that will give an essense of outdoor look.

For the hallway i am wanting something colourful, Geometry or has a bit of wow factor to it.

any help will be appreciated
