I like that leather color with blue maybe the blue te cat is ion. I do not however like the pillows at all . The "gallery " wall is really busy so IMO texture more than print for the pliiows and a simpler rug too. More like this then texture pillows even mongolian lamp in a color from the art /

I like a woven rug like this for an ecclectic space with leather.

light rug rather than dark to lift the feel of the space.

Large sizethan what you have so all of the sectional is on the rug.
