So you like purple? Please buy soft lavender curtains, or some with purple printed flowers, I've had dark purple curtains in my old house (3meter high ceilings) and it looks really dark when they're closed. Add a purple sofa or lots of purple accents to keep it calm and friendly. You could paint the window wall a deep eggplant (not the other walls because of light) with creamy curtains.

Have you ever thought about floating shelves? I think pairing a few floating shelves together would look great and would free up space in your living room. I really like the Eugene floating shelf from Bryght and I think it would compliment your existing pieces. http://www.bryght.com/product/160/eugene-cocoa-shelf

I assume that the pieces you have displayed in this corner are items that mean a lot to you. I remember being a newlywed and had to do solely with what I had on hand to make our house feel like our very own home. I added/replaced pieces a little at a time and finally completed the look I was envisioning. Below is my suggestion on how to get the items a bit more balanced to the eye. But in the end, I believe that the decors in your home all depends on how they make you feel in your heart when you look at them. The first one made use of some books and made sure the wall outlet was hidden within the wall shelf - assuming there is no constant need to use them. The second is an example where if you can buy only one piece to add, I suggest a piece to completely cover the outlet and take advantage of the conversational bubble style of the wall shelf. Have fun!
