It looks like you have a fence outside. Do you need the drapes closed for privacy, or are they strictly decorative? I would find a decorative rod in a finish that complements the other metals in the room and hang drapes from ceiling to floor, possibly in a textured neutral. It is hard to say without seeing the other colors, textures, and finished in the rest of the room.

Check out stores like West Elm, CB2 or even Target has some cool curtains for decent prices.

Stand back and take the picture straight on so we can see the entire wall. I'm thinking the rod should be hung higher and wider but until you post a better picture it's hard to tell
