Your pictures are very pretty, but absolutely USELESS when it comes to acoustic treatments. The shape of your room, where the doors and windows are (and how many of each), what sort of construction was used in the floors above and below, what you expect to accomplish with treatments - THESE are the sorts of things that will help in determining your treatment needs. You'll also need to elaborate on why the room sound is a problem now - "It's a little bright" doesn't provide much information.
Oh, and how much you want/are able/can sacrifice to spend will also matter.
Your pictures are kind of like posting a picture of a car and saying "Here's my pretty car. How do I make it go really really fast?". No help at all.
