I would remove the chair. It isn't the right color for the room and it blocks the pathway. If you want to add some color to the room I would suggest throw pillows. I hope this helps.

yes

yes.

Yes, along with the metal art above the windows. Just doesn't go with the room.

Drapery hung at the point the ceiling meets the wall (at right side) which would go across the door side also, at same height. (Art would have to go anyway for this).

Hello,
What a great room !
If you like the chair and want it to work it may just be in the wrong place....( the space is hard to judge , so this idea may not even fit )
It looks like you have two matching sofas ? Are they centered on the outside window wall ? It looks like you have a bit more space where the striped chair is sitting ? If so , can you ....
Pull both couches towards the space where the striped chair is,
Turn your rug longwise between the couches.
Take the striped chair to the other end of the room and angle it in the left corner ( not the door corner )
Move the black table and lamp over by the chair .
Add a tall green plant or tree in the other corner ( by the door )
Add small low matching tables next to each couch on the open /close side , with lamps if you need them .
Your art looks great it's hard to tell if moving the couches will make it be off center ! I hope not !

Btw... The chair highlights the colors in the art !!

Also you may want to push to the couches a little closer to the walls to widen the space so that the chair looks included .

Thank you all. i took from every comments...updates soon.

updates pictures coming

Updated pictures soon . I added 95 inch ivory curtain. i removed the metal piece over the window, and the chair. However, I'm still having a challenge concerning pillows. Shall i incorporate solid black, tan, gold, gray? I am also willing to change area rug as well as the gray ottoman

Please advise

I do not see anything wrong with the gray ottoman and rug. They add to the room with all of the white furniture and now ivory curtains. A pop of yellow, gray and black should work for your pillows.

Looking forward to pics. You really have to bring home pillows and see what looks best. So many times I have purchased pillows (thinking they would be fine) got them home and no, doesn't go.

My thoughts of pillows and add a solid black as well
