This Cabinet is $155 at Ikea. You could take the 4 items you had hung, and put them in a "shadow box", or individual deep frames to tie then together, to create I piece that looks more substantial on the wall, Then add a little ledge for photos, and you would even have room on the cabinet for the cool bottles that were on the floor, and that cool chest could definitely find a home as an end table, or entry table. You could also add a larger plant in a really nice pot in turquoise. The cut and paste renditions arent always completely accurate in scale.

I would take away those top arches and have builtins either side of fireplace, have the tv placed on a shelf on the built in, like in the pics, you don't have to have it above the fireplace, if room is small it will feel like it's coming at you lol. Panel above fireplace and hang some artwork or a nice mirror. Quiet like the builtins with the back wall painted

hi ....you can cover the wires with a cover cap or a handyman can pull those wires from inside the wall which would be covered by the wooden TV unit .You can put the speakers on either side of the TV and have very minimum things on the TV unit .You can hand some colorful pictures or posters on the side wall which would add character to the room

The sheer curtains looks good. The thick curtains can be changed into a plain one (neutral grey maybe) instead of a patterned one as it looks crowded. The tv can be wall mounted. Remove the decorative items kept on the tv unit. Reposition the black loveseat to near the sofa at an angled position. The cushions on the sofa needs some colors. Maybe you can match the colour of the cushions/throws to a painting . Painting can be hung on the wall above the sofa.
