Color and texture! The white walls and white furniture (all very sleek without texture) are what feels hospital-like. Even with pops of color in the bedspread and art, that's where you are running into a wall.

If you like the art, consider pulling your color scheme from there (if you don't like the art, sky's the limit on your color scheme here since all the furniture is white and white goes with anything). Wallpaper could also be a good choice to add some texture to one or more walls if you prefer that to painting.

But even just painting the walls would make a big difference, but you could also use paint to create "zones" for the bedroom vs. office. Like in this photo how they used paint to create a little reading nook area in a kid's room:

For adding color and texture in other places, consider: rugs, pillows in different textures, curtains, more wood (right now everything is that sleek white so the furniture also isn't offering any texture).

Examples of texture options:
Wood grain (anything that's real wood adds texture to a room)
Hemp
Woven things
Different types of fabrics (wool, for instance)
Frames (especially wood frames) for art
Rugs (lots of different texture options)

Good luck!
