The wood is beautiful. To me, the wood has an oriental-Japanese-inspired vibe. This wall's paint is nice, if your can match. Here's a method of choosing wall paint: http://www.lindaholtinteriors.com/2011/07/testing-wall-color-101/ Can you keep just the curtain panels and remove the sheers? At a later time, a non-patterned curtain panel the color of wall. I saw the art and I think it is OK, but not for this room. Perhaps in a bedroom? I don't understand the theme you have going? Giraffes? Clocks? If you like clocks, remove the giraffes and buy something like a large round wrought iron "clock". Note also the rug, pillows & throw as inspiration for your room. Perhaps the TV console in a lighter tone wood like their end tables (your room = too much black).

This Cabinet is $155 at Ikea. You could take the 4 items you had hung, and put them in a "shadow box", or individual deep frames to tie then together, to create I piece that looks more substantial on the wall, Then add a little ledge for photos, and you would even have room on the cabinet for the cool bottles that were on the floor, and that cool chest could definitely find a home as an end table, or entry table. You could also add a larger plant in a really nice pot in turquoise. The cut and paste renditions arent always completely accurate in scale.

Perhaps a large round table might mean a rug is not at all necessary. It could be a metal tray table, or carved wood like Rebecca Mitchell Interiors illustrates. Ideas also to consider, using multiple tables can be found at http://www.houzz.com/multiple-coffee-tables. I also agree with comments above that some color is needed on the walls. You could then hang round mirrors, or an unusual curved shape like RMI shows above.

One option, I would get a very large rug so that all the chair legs and at least one corner of the sofa is on the rug. I think I would also bring the table set away from the window a little more. I think there is enough space to place the two-seater opposite the table in front of the window. or bring the table forward toward the kitchen ....... With the sofa centered to the large window. They probably will not be opposite each other, but at an angle which is still ok. They might seem more functional for the table set to be closer to the kitchen. Another option is two rugs in wide runners. Creating a walkway through the center of the room. Still thinking the sofa center of the right window. Just some ideas :-)
