Are the floors tile? I would add a rug to make it more cozy and home feeling. Add some wall art or mirror or something on the walls. Maybe a side table with a lamp. You can even add a teal color pillow on your couch since that is the color in your house.

Your home has nice pieces but seems overly formal especially for a young couple.

Recommend you remove the tie backs from all of the drapes.

Turn the dining table so the length is with the sofa. It will look more balanced with the rest of the room.

Your walls could use some art. Put the little snapshot holder in the bedroom. Add a large print over the chest.

Add a bowl on the chest to hold keys.

A big bold painting brings serious flair, and can instantly change the vibe of any space. Whether hung above a fireplace, sofa, or elsewhere in the room, a painting can create a focal point with impact and add both color and dimension.

Here's some suggestion for your wall you might like......to know more about my Art work and collections please visit my shop on Etsy website -

You might think about moving the chairs to the bedroom and adding two more comfy chairs to the living room.

This makes it look better I think, because it has a nice flow. When couch is facing the window, I feel like it is separating and it seems like its own little space. But as someone mentioned above, I would turn the table sideways.

Much better with the sofa turned with its back to the wall.

A rug would also define the living from the dining area.

You're going to need a coffee table.

End tables

Floor lamps

Art that's 2/3 to 3/4 the length of the sofa.
