That wall is everything that is good in the world. Truly.
Oh, and the chair's placement creeps me out a bit (what, is someone gonna watch you while you sleep?)
I like the bright colors contrasting with the white. I like the mix of vintage and contemporary. I like that it looks like someone's personal space, and not like a sterile, perfectly designed space.
Is this collection of art hung above and beside a bed complete, or is it an ever evolving grouping that can continue to spread across the walls? I love the random feeling of the images and the inclusion of the very tall image on the right.
