Thanks!! I like all the ideas! I'm thinking three or two frame photo/color art above the cough, and then a grid-style gallery wall along the wall with the front door that has the black and white with the accent blues color or something like previously posted. Interesting idea! I think I just need to commit!

Roman if you keep posting that you are open to anything, flexible, happy to receive feedback and quickly take action based on that feedback you may just end up with wifey from this site!

Would add wainscoting the same white as your trim colors and then you might consider an accent wall color above. If you add anything for purely decorative purposes, then, because this is a high traffic walk path, consider something not breakable if bumped and knocked off the wall either in lieu of or in addition to wainscoting -- perhaps even a mural: https://www.wayfair.com/decor-pillows/pdp/latitude-run-euan-autumn-forest-wall-mural-ltdr6645.html either alone or to create a faux window wall with a view. https://www.google.com/search?q=mural+used+to+create+faux+window+wall+with+view&client=firefox-b-1-d&source=lnms&tbm=isch&sa=X&ved=2ahUKEwi97NPikcHrAhXJlnIEHZD_CYQQ_AUoAXoECA0QAw&biw=1325&bih=648#imgrc=X77Fk2IlZ_ie8M

I think an Ikea hack or something along those lines would be perfect there. and you have the depth. get ready for a bunch of pics! here is the Ikea hack w/the Billy bookcases (all of these how to's are online) Ikea Havsta no window, but it would make a cozy reading nook And then you would tweak the look you want. add in the shiplap, or instead of the tv, do artwork, or shiplap This one is really unfinished Oak base kitchen cabinets, put up on a pedestal base, trimmed out and painted. DIY wood countertop you could do more of a buffet type of cab. On one end you could have a little desk area you could do the entire wall area w/wood tiles, or plank wall trim or even an accent color do something as simple as this or buy something like this from Ballard I like this one too. if you do a white tongue and groove and build it out for a recessed niche w/natural wood shelving, you'll get this. (studio mcgee!) this is gorgeous. I'm sure you've seen it. It would act as storage. what you could do for the middle is make it a desk area for homework and studying down the road. But I love the dark moody color in the midst of all your white.
