This is from 'briankosena's photostream' on flickr. He explains that although the children had been brought in for a rest, this little girl didn't seem to need one.
She is resting her head against her arm and the grid pattern is her uniform, which isn't quite accurate.
Her ears aren't quite right and her nose and mouth are slightly too far to the left but I'd already spent 40 minutes on it. (Great exercise, Gry: thanks.)
