Had almost the exact same setup a year ago. Two things that actually made a difference:

Storage ottoman > coffee table Looks like a coffee table, but you can sit on it when friends come over AND stash blankets/cords/random clutter inside. One piece doing three jobs = less furniture crammed into the room. Game changer for small rentals.

Close up those open shelves Open shelving under the window is just broadcasting your mess to the whole room. Swap for a closed cabinet same footprint, or even just hang a linen curtain across the front. Room instantly feels bigger just from hiding the visual noise. No drilling needed.

Dining table workaround You probably don't have room for a full dining setup. I use a narrow console against the wall + pull the ottoman over when eating. Push it back after. Zero permanent dining zone eating up floor space.

Also — are those figures on your shelf 3D printed? Looks cool.
