Do you have photographs of windows that need curtains? Would you post them here?

You have a nice picture on the opposite wall. I cannot tell from the angle whether your lamps are too short. They do seem to detract from the painting, you might want to place them elsewhere and find skinnier lamps. As for window treatments, have you considered a geometric print for your curtains, like this:

You could try a mirror between the two windows to reflect the painting. Something like this picks up on your orb on the table:

Not sure of the size of the room, but two sofas seem overwhelming. When your budget allows, replace with two club chairs for some variety.

Thank you. Any suggestion on where i could find these drapes

Believe it or not, they are from Walmart-Better Homes and Gardens brand.

tean, Nancy's idea for the lamps is spot on. Yours are out of scale with the sofa and the art. You could either do two floor lamps, or get a longer sofa table and do two taller lamps farther apart than your current ones.

Tip: you don't have to fill every space in a room. The art and two properly sized lamps are plenty for that wall.
