What a pretty room! I love the red chairs and the wall color. I would either remove those shades or get curtains to cover them. Quite likely from the outside they look like there are brown paper bags at the Windows. Could you place a small table with a lamp between the two chairs? I would try to use the floor lamp somewhere in the room. Lamp light is very important . You can then turn off the overhead light. Are you planning to get a rug?

I would not do an accent wall in this space.

I’m looking out the window at your glorious view and wondering why you are trying to rivet attention inside the smaller space of the room with dark graphics, flash things, and saturated colors rather than bringing in more of great wide open to extend the space. In particular I suggest removing the two black chairs near the window that sit there like a wall in favor of chairs lighter and brighter, with a more open profile. If you absolutely don’t want to give up a deep comfy lounge chair near the window maybe something like this or in a very light grey If you want to tile the base of your bar, borrow the cobalt blue of your Murano glass, which will send the eye back out to the view. Personally I would do something less expensive than tiling, like paint or peel-stick wallpaper Tuck more of the rug under the white sofa.

A paneled wall looks best on a windowless wall. There are shallower media cabinets that will fit your space, anchor the tv, and provide needed storage.
