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.

At first glance I think that if you are going for a modern look, I would suggest nesting tables instead of a coffee table to create interest. Here are a few ideas for you: http://deciture.com/the-amazing-set-of-3-wood-nesting-table/ http://deciture.com/gilbert-galvanized-nesting-tables-set-of-3/ http://deciture.com/flouressa-mirror-top-nesting-tables-set-of-3/ http://deciture.com/brighton-mirror-top-nesting-tables-set-of-3/ Hope this helps you!

There are lots of nice cordless lamps. What if you take the picture to a store that just sells lighting, and see if they have something similar in their catalogs? It would be expensive but maybe worth it if you love having them be the first thing you see when you come in the door.

Your setting is good but could be better.the centre table is a misfit.you can use 2 level rectangular table either white poly paint one level and the other level glass or black paint or poly paint.keep the length of the table after leaving approx 16 to 18"on either side.the width can be20-22 " and ht 16".the cushions can be change to black and white design,with a dash of red.a nice rug with grey,black and white geometric design will enhance the effect.brown does not go well with white.i hope this should solve your problem.once you make this change.you eye will pick up the other flaws.
