主卧室改造

主卧室改造, 请你帮我出主意。
总觉得主卧室太一般。想花点钱改造一番。以达到让自己赏心悦目的效果。自知自己没有艺术家的眼光和素质，可否借助大家的智慧，帮我出谋划策？在此先衷心感谢大家的畅所欲言。
我的主卧是个套房。如图1 所示，共4个sessions.

Here is the picture of session 1 and 2.

Here is the picture of session 3 and 4.

书架显得很乱。我想把书架改成矮柜。这是我用photoshop画的视觉图。

我的担心是这是墙纸画。效果如何？能否请有经验者给点建议？What suggestions you can give to me if I don’t use 风景wall paper?

If I exchange the session 1,2 to 3, 4 like this.

Do you think the one room will be tight while the other room will be too empty? What suggestions you can give me to avoid it?
