Sophisticated start. You could go with black and white photography, architectural pieces, art pieces- anything you love on the wall. Then, add pillows in the colors of the art work. If you want to stay more monochromatic, think in terms of textural interest, such as a shag area rug, pillows with seam detailing, etc.

I would embrace the element, but I would get rid of the wood chips. I'm thinking back fist sized river rocks. Then I would get a tallish flowering tropical such as hibiscus and add a few ivy plants to grow between the rocks. Additionally, a small water feature might be nice. For me, the bigger problem with the entryway is the door. You have an obviously contemporary home, yet you have a -very- traditional door. I would want a wood door with some sort of art glass element in it. The wood would of course need to be stained to match the existing woodwork. The door will be some big bucks, but it would remain regardless of flooring changes. These two doors are not specific recommendations, but examples of the type of entry door I have in mind. Best wishes!

WOW!! So funny! It's a dream to see the All Blacks play - I can't imagine getting to watch in a set up like this! Perfect blend of masculine and feminine, well done!

I grew up with these panel doors and remember the glorious day they were replaced by a curtain. So if you are open to the idea, for ease of use, least effort and cost that's a simple fix that your daughter may want herself. The top cabinet doors can be considered a cornice for the drapes, and can be upholstered, maybe in the same fabric as her window curtains, and a simple drape with coordinating stripe on the bottom. Search "upholstered doors" on Houzz, and you will see ideas for nailhead trim, tufting, etc as well. You may also be able to add thin trim molding in a custom design to make them special. Good luck!
