My eyes are having a tough time accepting pink trees amongst a mostly green world, but I'm sure I'll grow to love it. I can't deny that the extra colour is nice, and the flowers, butterflies and other details really make the world less 'sterile'!
I love the giant book! I'm wondering if it too needs a bit more colour though. For example, maybe the circular 'metal' podium under the bookcase could glow with some type of magical lighting? I'm not sure.
