Move the great floor lamp to another spot, also the cabinet.

Because there isn’t a lot of depth available do shelving.

Combine your other post about painting the fireplace here.

You will want everything to jive.

Every wall doesn't have to be filled with decor. I would consider moving the floor lamp to end of the sofa where reading might take place. Doesn't really serve a purpose in this corner.

An Ethanol Wall fireplace would be a perfect fit in your space. Ethanol fireplaces do not require a gas line, propane, or a flue. They create the ambiance and feel of a fireplace without the mess!

Looks to me like you need a whole room plan. And for that,we need some whole room pics.

I like lamp where it is, and maybe you can read there. It lightens a dark area, and has an upward glow. If a smaller room, as I've had, you have to eliminate an end table, etc... sometimes. I like what you've done: art and pillows and tv unit....
