More pics of the room would help. But with just this view, I would get either two larger lamps for the sofa table (yours are much too small) and if you like the art pieces that are hanging, I would move them one above the other in the center of the wall between the lamps. If larger lamps aren't in the budget, I'd still move the pics and hang them a bit lower, with the bottom of the lower one (when it's stacked) maybe 6" above the table or back of the couch and the other above that with a couple of inches between them. Cut out paper the same size and tape them on the wall to try arrangement. Post back here for feedback if you need it. Can't see what's on the right side of the fireplace, but the curio and floor lamp look kind of crammed together on the left, so I'd move one or the other of them elsewhere. An idea for better sized lamps

I think in your kitchen you need more contrast and color. Easiest way is to change your hardware to black (or color it black). You have warm colors in your kitchen and cool colors in you living room. You can use the warm colors like red or you can use cool color like blue or purple. It depends which color you like the most. For example you can use blue for shades in your kitchen and some kitchen decoration (as long as you have the same color in you in your living room) then add something orange, red, or Gold (warm-similar to your cabinet's color) as an accent to your living room. So you need more warm color in your living room and more cool colors or contrast colors in your kitchen. I hope it helps.

I thought we were dealing with a loveseat before. The sofas should each be 18" or less from the coffee table, but I'm concerned that the traffic path through the space will be a bit circuitous and blocked up, and TV watching won't be good unless people stretch out on the sofas. I think the "L" you had originally might work better and then put the two chairs with those tables flanking the FP or on the window side to get the "U" I suggested above. Use a floor lamp between them if there is an outlet under the window.

I would not float the sofa with back to entries and windows + its back to the fireplace - with a view of a tv in a corner. From a Feng Shui perspective, I prefer not to float the sofa at all, if it can be avoided. So this sectional placement - with sectional facing the windows and main entry as well as facing the fireplace, anchored on this wall would be my first choice if feasible. With a possible additional seating area on the other side of the room Or alternatively, float the sectional this way, with a sofa table to anchor it. If the tv is over the fireplace, you can possibly use this mount. There is also a motorized option. https://www.dynamicmounting.com/product/down-and-out-manual-mount/
