You already have blinds so do you really need curtains? You might think of spending the money on upgrading the art over the sofa. Hang it 6 inches above the back of the sofa. A mirror isn't the best choice for over the sofa. You need to add some color and interest.

Your TV is hung way too high. It should be lowered to fill the space that's left blank now.

Great! but that wasn't what my post was asking.
