Center the tv and console on the wall, ignore the empty corner and add art in something OTHER than brown to walls.

Add lamps.....side tables to your seating, or standing lamps, all your light is ceiling...........and HARSH.

Your pictures aren't great, can't tell if you have a rug or not, That is a good place to begin for some COLOR.

Part of the reason that the wall looks off is that your console is undersized. And the tv looks a little high as well. If you get the proportion correct the wall will look more balanced.

Another issue is the lighting. Overhead lighting casts shadows that give a room a commercial vibe. Table lamps and floor lamps will add a needed layer of light and add a decorative touch to your room. Definitely put a floor lamp in that corner.

Curtains, properly hung, will help make the walls look less bare as well.

Then add some art to the wall and the space will look nicely finished.

It seems as though one family member would like a nice cushy dog bed in the corner.

Yes, buy that baby a bed pronto. 🐶❤
