Are you speaker the same distance into the room? It may seem like splitting hairs, but accuracy in speaker placement is very important.
Also, record your speaker placement in a journal or on your computer for future referance.
Your speaker place in picture looks to be about as wide as you can place them without losing your center image. You might even try to place them closer together than you think you need to. I did & it does make quite a difference to the soundstage. I know will help the firsr reflection points to have your speakers as far as practical away from windows.
It looks like a barristers bookcase behind right speaker with glass fronts on the bookcase. You might try to move to the side. I think that is playing around with you soundstage. And it won't cost anything but sweat & time to play around with it.
BTW, your harwood floors look awesome.
