ooh lala! - inspiring wall decor

ooh la la! Look at these wonderful wall decor ideas. 

The mountain wallpaper (the photograph on the left in the diptych) and the wonderful wallpaper in the kitchen below are by Minakani Walls. What creative ideas that completely light up a room!

I love this wall decal of a tree, especially its placement behind the couch. It creates a whimsical and pastoral sensation within the living room. 

Any ideas of another creative way to revamp a wall?
