That is a lot of big furniture in a small space.

I would add art above the sofa.

I would add color in the kitchen via tool caddies, tools, dishes in the glass cabinets.

Not a pro. Add art that appeals to you, and then you can add throw pillows in one of the brighter colors in the art (for example, a yellow or a red).

Color if you like it. Another option is texture (colorful or neutral) -- drapery panels, lamps, art on the walls and table, plants.

Consider adding sun catchers on the windows.

You could add narrow end tables with blue lamps and even light blue lamp shades.

Definitely add color! Your space really needs it and beautiful art would be a start. Colorful throw pillows would help as well!

I agree with @einportlandor You definitely need some texture added to the room in addition to colors. Oh, and lamps for end tables. What is on the 4th wall ?

A patterned rug could add some pizazz and maybe pick up on your navy accents.

Yes. The gray is dull.

I would start by changing the rug to add some contrast and of course add some lamps.

Get a colorful rug, some art you love and then use colors from the rug and art for accents and a few pillows like 2 per sofa.You need lighting in the way of lamps and get rid of the fan and add a ceiling hugger light there too.. If you ever need to go shoppong for furniture again get a sofa and 2 coordinating not match chairs and forget the loveseat which really is a comfortable seat for one.I like the color of the leather it beats black or brown for sure.

Yes! You need some color. Pull a color (no more neutrals!) from a new rug for pillows, a colorful tray for the table, lamp bases, etc.

You need lamps to provide light by the sofas. The overhead and sconce lighting is very harsh.

Lisa unfortunately the wall is about 5 feet back. Hard to tell in pic. There no place to plug lamps in.

There are no plugs on the wall behind the sofa???

When I've floated furniture I've used extension cords for lamps and ran the cords under rugs and furniture to keep the cords out of harm's way.

Vis á vis lamps. You could look into installing a floor plug closer to the sofa. It is not advised to run cords under carpets since any wear would be hidden and create a potential danger.

There are plugs but it’s actually a jagged wall and a walkway

I see two lighting solutions.

Put a large lamp on the console. Easy.

Next, get a runner for between the console and the sofa. Buy a lamp for the round table, run the cord under the sofa, under the runner and then under the console to the outlet.
