Need Help Rearranging My Living Room?

I need some help rearranging my living room. We have a room that has several windows and is very difficult to work with. I am hoping to make this room a bit more cozy and inviting as well as improve the lighting.

The entrance to the room has a small place. The TV is placed in a triangular shape between the wall and the window as that is where the plugs are. The little wall like thing opposite the door is about 4 feet tall and I place a silk flower pot on it.

Please help with the placement of the couch, etc., to make it more inviting. We have two kids under age of 5.
