A patterned area rug under your table, a colorful centerpiece and a light over the table will help define the space.

It looks like your house could use some colorful accents. Art, throw pillows, vases, etc. will make it looks less blah. You have a nice space and a great start, you just need to add some personality.

Also adding floor lamps and table lamps will help warm up the space. If you strictly use overhead lighting it will be harsh and make the space feel like a store or office.

I don’t know why, but your photo is sideways. Can you take another and one of the living area? It looks like your sofas are too far apart. Maybe if they were closer together and had a coffee table between them, it would read as more of a unit, and define the space better.

you can also place a sofa or chairs with their backs to the table.
