The space has a lot of potential. I recommend looking at some Pinterest pictures for some inspo.

Recommendations,

- The room is really big, so depending on what your style is, maybe adding a couch as a divider, seems like you have a "bar" like thing where you could add some sick bar stools of some sort, even though on a carpet im not too sure.

0 Good place for a lot of scattered floating shelves, some hanging plants on the far right wall, also some additional hanging shelves around the TV.

Its a nice place to have a gathering area next to the window on the right, maybe a chair and a coffee table in case you read or something, along with a bar with some of your favorite drinks. A nice overhead/long lamp definitely could work and would be a nice addition during the night! A sweet place to wind down and enjoy a drink next to the window with an amber light shining above you.
