What has to stay and what can go? The mantle is odd. The sofa and loveseat are too large for the room. Draw a floor plan with all the dimensions and door and windows indicated. I think you need to get the furniture placement correct before adding decor

Are you looking for some budget friendly accents and furniture rearranging or let's kick the furniture to the curb and do an HGTV extreme make over? I think it is just the camera view that makes the couches look set at weird angle. Do you have enough room to float the loveseat closer to the fireplace and tv so that it makes an L with the larger sofa? Then you could make the walkway behind the seating and even have a sofa table or small shelf behind the loveseat. When my kids were little it was nice to hide all the toys in a basket behind our sofa and we could enjoy the fire or TV after they were in bed. Could you use a better end table with a lamp in the corner between the sofas. and use that cube as a coffee table/foot stool? do you need a nice rolling chair for the computer hutch/desk? There are some swivel leather chair that recline to be a lounge chair and a desk chair. Are you just looking for color ideas? Bright art ,pillows and throws are ways to brighten the dark leather and bricks. You have a lot of Family photos in matching black frames. Those could be arranged into one big gallery wall or put the largest over the mantle.

The mantle is set alittle high but it matched the the TV cabinet which is well placed. ( I hate those TV above fireplaces.) The darker brick contrast with the lighter wood. While not a fan of painted brick, something like a German Smear or thin limewashing would lighten the brick but still let some of the terra cotta brick color show through. ( this can be a simple as sponging watered down house paint over the bricks.) Lightening the Bricks and adding a larger mirror would bounce more natural light into the room from the patio doors. Could you switch the placement of the loveseat and computer hutch so that sofas faced each other?

We can offer fresh eyes and ideas, but you live there and need to make choices based on your needs and budget. So what are you wanting to improve, just freshening colors or radical rearrangement for traffic flow and use of space?

What do you want from us? New stuff , new layout what ?????

Please give us more insight on what you are wanting assistance on.

If you only watch TV at night, you might try a drop-down screen over your sliders.

I'd add a rug, aiming for pulling in the bricks and browns you have and adding some more color. I think the mantle and TV cabinet are the wrong shade for your browns. I'd reupholster your white ottoman. It's very bright for the earthy tones in the room. I'd add a coffee table in front of your brick sofa. I'd clean the brick between the fireplace and mantel.

The tv and tv stand just seem to be stuck on. Will suggest you mount the tv on the brick wall adjacent to the fireplace instead.

Some thoughts:

--You have four visual black "holes" in your living room: two dark couches, TV screen, firebox, tall black bookcase. These suck the light out of the room. Here are some fixes.

--The fireplace is a wonderful focal point, which is not arranged in a pleasing way. Bring down the mantel. Get two bookcases or console cabinets in the same wood finish to flank the fireplace. Put the TV on the left. Fill the right bookcase with curated stuff from the big bookcase in the room

--Bookshelves even with the mantel:

--Lower the mantel and put one art work you love on it, not all these bitty items. Put the TV on a console and float shelves on the other side:

--Fill the firebox with birch logs to lighten the firebox. Or put a white globe lamp or tall flameless candles in it.

--You have one massive sofa too many. Choose one and float it to face the reconfigured fireplace. Get two comfortable armchairs to face the sofa or the window Anchor them on a rug and get a nice coffee table.

--Paint the huge armoire piece white or replace it with a low cabinet. It takes up a huge amount of space. What do you use it for?

Rugs: Choose a large enough rug that coordinates with the golden floors, red brick fireplace, and whatever sofa you choose. All furniture should fit the front legs on it. This palette would go with either sofa you keep. The brownish red echoes the fireplace. The gold echoes floors:

I guess OP has gone AWOL. She/he certainly didn't give us much to work with a vague question. For anyone following this posting here's how to post a Design Dilemma to elicit specific suggestions:

You need to show the whole space—all four sides of an entire space—even if it’s about one specific Dilemma. Commenters need to see doorways, windows, closets, finishes throughout the space to make informed suggestions. In open spaces, Commentors need to see adjacent spaces like living, dining, family room areas that adjoin a kitchen. This is so finishes like cabinetry, paint, and flooring harmonize in the while space.

State right at the beginning what the room will be used for and who will use it. State the non-negotiables at the beginning, what has to be kept. Give some idea of the budget. And provide approximate measurements

Keep in mind that you're inviting some design pros and people with a design eye into your home via photos. If they walked into your actual space, they would take in all of it: all four sides, doorways, floors, windows, ceiling, built-in fixtures, lighting, trim--the "givens"--then the features that can be changed--furnishings, paint, art, rugs, decor items, etc. It's all one first impression. Same thing with photos. That's why it's important to provide well lit photos of the entire space, taken from all sides of a room regardless of the size of your problem.
