You need ART! Pop art? A sculpting on your table? Some antique kilim pillows on the furniture for pops of muted colors.
Live potted plants are always great.

Start with a favorite color or two (not beige). Add a throw, some pillows and a live plant in a planter. If you can't decide on a color, start with some art and pick a shade from the art.
By the way, you can get an inexpensive area rug from Home Depot or Lowes and then if the kids drop a few crumbs you won't be devastated.

The room is lovely, but all I see are hard surfaces and right angles. I agree you need a rug and you should purchase a soft throw,in you favorite color. I would also add some throw pillows - perhaps some curves if only in pattern of the in the rug or pillow fabric. I agree you need a painting over the mantle, but take your time and find something you love. Other than the wood mantle, I see a lack of natural or outside elements. Maybe a large round basket on the coffee table. Since you probably don't want to put anything dangerous on the coffee table, I would add either a pair of sizable candlesticks, urns, ginger jars or hurricanes to the mantle. If you have safe place for a plant, include that also. Although it may have to go on the mantle. Additionally you probably need some end tables- at least one. I would look for sizable round ones - they don't have to match and eventually lamps. Hope this helps.

GREAT start. LOVE Everything so far. :)

To start you have great furniture! Now, spend some money on a rug. Do not get an expensive one just one that looks good. Then add art. Paintings, sculpture and some nice hand blown glass. These things give a home character and style. It reflex you and your lifestyle.

Thanks for the feedback. It's motivating... Wish I could go shopping right this minute!

Great space! I would add mirrored vases to the center table to add shine. Throw some colorful pillows and fresh flowers to accent on the mantel and anchor the space with a dramatic art piece. To soften the space add wood to warm it up :) enjoy

Great bones, but definitely now it is time for some colour and warmth. Paintings are good to choose colour from and build a colour scheme around but as others have said, take your time and choose carefully, you can't rush this sort of thing. You definitely need some end tables for guest comfort. Lamps would be good too, but probably out of the question at the moment. I'm not sure of your shops but check out $2 shops or maybe places like Walmart for inexpensive timber ornaments that won't break easily and you can change out at a later date. Amazing things can be found in these places with a good eye and placed just right. I always recommend plants, but I am a greenie at heart. You may also be able to find a rug that can be taken out and hosed down, I have heard of these.

Try Google, the best place to start shopping to get ideas, find where to buy things and save hours of legwork.
