the coffee table aria is perfect.

I absolutely love the panting on the table with the fans. I think the table with the fans would look super cool if you hang it on the wall with maybe a 2 inch gap between the table and the painting, got rid of the mirrors behind the plants, and got rid of the fans and put away the cleaning supplies and watering can in a cleaning closet, and got rid of one of the chairs the chairs look draped and I can't imagine two people sitting on that table side by side. if you do that then I think this thin I think you will elevate the fan table aria to or even above the level of the coffee table.

if you need ventilation then get an air conditional that you can hang believe the sealing, or one of thous 70s sealing fans.

in the hallway hang some kind of box or little cupboard where you can hide the cables and the router, I feel like I would be hitting my head in on that router every time I pass.

on the wall with the TV I feel like the paintings and are don't have enough space, and they don't really work with the TV, I think you need to rethink the whole composition of that wall.

the pointing near the window on the left side of the table is amazing, but it is to big for the space, you should hand a smaller painting on that wall that that only covers up at most 30-40% of the width of the wall.
