Without seeing the rest of the room, I think picking up the blue in the rug would complement what you already have. Pretty!

I agree pillows in the blue accents or even that rust/orange in your rug would look great. Some examples from Crate and Barrel. Adding textured pillows make the space feel cozier too.

Here's an example of a pillow combination in blue.

I like the look of rust and grey (which I think is also in your carpet). I think they feel warm together and would also add coffee table books to the bottom of your table and reacceessorize the top, for a really nice look.
