Suero, I like the gray idea... Most of my pictures have gray in them as well, with some "shots" of color. I googled "gustavian gray" and got every color imaginable. I'm thinking a light to medium hue. Is that kind of what you meant?

Your room is very nice. But I think to fill that wall with art/photos, you're either going to have to have very large pieces or many of them. It's not possible to tell from the one view, but the first thing I thought when I saw your pic is that I would move the head of the bed over to that wall. I am assuming there is a window on the other side of the bed to match the one we see? If so, then that wall between them is much smaller for hanging art. It also might be possible to partially block the view of the dog crates if they are behind the bed when entering the room (or could they go on the wall the door is on, so they aren't so prominent from the door view?) Placing art above the dog crates is going to look odd and unfinished to me.

is one of your objectives to create an entry-way and block off The View into your sliding glass doors? If so can you supply more pictures? You've gotten great advice so far for the TV wall. I'm also a huge fan of sliding a piece of art in front of the TV, they have nice rails you can install above your television.

That table is far too large for the room, sorry - I know you just bought it. Your room would lend itself better to a 54" to 60" round table. Suggest you put that table back on Facebook Marketplace and go that direction. Over-crowded dining rooms never look good.
