I like the two different wall colors. Perhaps pink for the closet? For a similar paint shade, try 'Razorback Road' from the Dulux 'Colours of New Zealand' range. Available through Guthrie Bowron stores.
Mommo Design has a bunch of inspiration for girly reading nooks. These quiet corners contain fluffy pillows, rugs, cushions, usually a canopy, and of course lots of books. I think the idea is very cute and I'd love to do this for my daughter's room.
