Since it's an open floor, do you have an additional photo to show the rest of the space? What other decor do you currently have in place?

HI -- Your sectional is wonderful and big so keep the room a little more minimal . Don't go over board with everything being purple . The drape panels are not good --- can you use them somewhere else and just find some possibly textured but plain light gray or off white drapes ? Have them hung wider and fuller but still ceiling to floor length . Cushions on sofa are great and you can add a couple of light grey/white fur ones and a same throw . A nice round tufted ottoman and a "L" table or two . Maybe an arch lamp in a chrome finish . Find another place for the clock and maybe have a painting or two stacked pictures . You didn't show any more of the room or furniture so commenting is hard about anything else .

If you want to go with purple(which works really well with grey) maybe a different shade for the pillows & throw might work. One that would pop more against your sofa. Also maybe a round white coffee table to coordinate with your entertainment center.

The curtains need to be doubled for each window. Add another panel to each window. Too bad bottom border cuts off almost exactly behind the sofa. All a solid color or a design.

See how full these are?
