First, do you own or rent the condo -- are there any rules prohibiting you from painting any part of it? If renting, do you really want to make permanent costly changes even if you're permitted to do so? The gray doors and trim actually go well with your black countertop and furnishings and don't clash w/the brown sofa. If you paint any trim, you'll probably need to paint all the trim ... and probably the doors, too. This would be expensive to have done professionally and any mistakes could cause a renter to lose their deposit. Consider leaving the trim and doors as is and, if permitted by whatever condo rules with which you must abide, repaint the walls instead. If you do decide to paint the trim white, Benjamin Moore makes a stark, true decorator's white -- likely a better choice than the off whites, many of which can have a pink or yellow hue to them. The kitchen walls -- backsplash and over the overhead cabinets, are a distinctly separate space than the rest of the condo. White subway tile backsplash is worth considering but is more costly than painting -- something to consider, especially if you're renting. With bold black countertops, you might consider painting all the kitchen walls your favorite bold bright color. Then you could paint your dining table the same color, or perhaps just the top that color and the rest of the table black (as many of your furnishings are). Behind your stovetop on the wall between it and the hood, you should probably add a panel designed for that space -- easily cleanable and flame resistant. Stainless steel would be best -- the white over metal ones can more readily show scratches and/or stains. In such a small living room area, a rug is optional -- the seating area is pretty well defined. It wouldn't hurt to walk through a few stores and see what's available in a size the same width as your sofa and long enough to extend from beneath the front legs of your sofa to beneath the front of the furnishings opposite the sofa. Wouldn't want a room sized rug -- even if it didn't interfere with opening the door, extending it beyond the sofa into the traffic area from front door to kitchen/dining area would be counterproductive to the purpose of an area rug for a living room.-- to define a sitting space. With little seating, a single throw pillow with your favorite colors would suffice. Plain, then -- metal (think document frames) for art would work with what you have or you could choose something without a frame -- perhaps pressed metal art. I googled pressed metal wall art trees images https://www.google.com/search?biw=1366&bih=650&tbm=isch&sa=1&ei=0I1QWumOII2-zgKtnozgCQ&q=images+pressed+metal+wall+art+trees&oq=images+pressed+metal+wall+art+trees&gs_l=psy-ab.3...6401.7143.0.7285.6.6.0.0.0.0.45.259.6.6.0....0...1c.1.64.psy-ab..0.0.0....0.5INBPx3xz0c You could replace trees w/any object or subject that reflects your interest to see what might be available. What interest you? Mountains? Beach? Hunting? Biking? Wildlife? Music? Then, if you decide that metal art is something that interests you, change "images" to "shopping" to begin your search in earnest. Modern wall shelving, including but not limited to box shelving, can be both decorative and useful. Update us -- let us know what you decide to do and post pics.

Sounds like you and hubby aren’t on the same page. Buying a table, without ability to return is red flag to me. He bought that rug too without your involvement. The rug is wrong size and style. No photo of the table. But better sit down and talk about this and reach some compromises otherwise, these situations can fester and get ugly over time.

I see a few things that aren’t horrible, by any means, but could be changed. Mirror and sideboard, for instance, as mirror is too large for the sideboard and it overwhelms the room, reflecting the t v. Try the art over the sideboard and add a floor lamp where the plant is, as it will do double duty for the sofa and the art. Have you ever thought about adding a floor to ceiling strip of trim to separate the dining area from the living area and painting that wall a color? Something like this with a couple of white shelves on that wall?

An observation: the chandelier in the dark room doesn’t work with the sputnik one. Something like this light would work. Rectangular in shape, so great for over the table, and the same metal as the sputnik. Assuming the dark room is the dining room, then bring that color into the living room with a sofa in that color. Art can be whatever you love, and considering It is a playroom, something fun would be appropriate.
