The simplest thing to do would be to get rid of the small stuff you have on your wall and replace it with something big. You might try a big mirror with a black frame. You need more stuff up high, so consider putting something on top of the high shelves. I really like your muted colour scheme and the pop provided to the muted scheme by the comode with the green and red. The green picks a little out of the couches. The problem, from a colour point of view, is the yellow-tan cabinet and coffee table. Having three cabinets on one wall is brobs too cluttered. You MIGHT remove the center cabinet, replace it with the comode to cover the switches, then put something big to balance the cabinet on the left, or, better yet, get rid of it too. You could put down a rug with matching colours.

A houzz contributor, not too long ago, had made a wine rack out of 4'x4' wooden pallets, that are used in the US to move a load of goods with a fork-lift truck. Perhaps they have them in your country. He cut them in half so they were only two feet deep and stacked them up to high counter height. The wood would be a nice contrast with your concrete, might add a little warmth to the space. cascio.offsite@gmail.com
