Erin McGuire's adventures in blue

Last May I did a post about Erin Mcguire's work at the moment I found her blog and was spelled by her art.
I went back and was enchanted again and as it's always hard to chose two in a good collection I decided for these because I love blue.
At least there is a criterion not very orthodox but a criterion.
But notice that the "action" is not in blue. The cat and the boy with a book in his hand as a shadow and the light that comes from inside is amazing.
