Pull the sofa sofa forward to float perpendicular to and a 18" or so way from the wall with the art. Use the upholstered footstool with the chair and pull them forward too. Put the corded gear in the shelves and eliminate that metal shelf/cart and the coffee table. The sofa appears to be a lounger, so you really can't use a coffee table with it. You might buy a couple of skinny "C" side tables to use at each end of it for putting down drinks, etc. If budget allows I would permanently close off the hall access by the blue wall. I'd continue the blue paint throughout the room. It adds a lot, works with the brown sofa, and you seem to have natural stopping points so you don't have to take it into the kitchen .

Hi nice size kitchen, horizontal lines in your kitchen will make already long kitchen look a bit longer. looking at the pics of your kitchen it looks like u have a lot of horizontal line i would install the tiles lines vertically to bring the balance back. Number of lines will depend on the zones and the kitchen enterance along with dining furniture or vertical wall lights in the room. u may need to take a pic from the enterance of kitchen and draw a few details on the pics then work out the lines. Vertical lines are easy to over do so be careful. good luck

check with the maker of your wood heater and with their specific guidelines you may be able to have a built in arrangement around the heater although the flue will need to be enclosed with a frame and wall cladding to have the mantlepiece which would then project a long way into the room? but, unless the maker guarantees the safety of your fire enclosed under their guidelines i suggest you may be better off to consider a new heater specifically designed to be built in with a flue that can be directed horizontally through the wall or up through the old space behind your heater but they must be installed by experts to ensure safety

I like the photo of the chair at entrance with green wall behind and round timber mirror above, all you need now is a large simple pot plant, round perhaps in white, with something like a rubber plant or large leafed variety, or Mother-in-laws tongue perhaps then add a white marble top small table on the other side of the chair, closest to the door with legs to match or similar to the chair. Remove the timber hall table all together and the letters and dragon fly on the opposite wall. That should do it. Pot plant examples photos to follow
