Tender Coolness.
Optimum choice of colors and lovely character.
Seems like youngsters acting like children have become a recurrent trait of your work... I can't see what'll be next!
BTW, you've got the most of that lined paper. the blue lines smugded by the water blend with the picture perfectly... Maybe the color "blue" got stuck in your head when creating the picture(I suppose that's why the guy wears an eskimo-like coat).
Horray for you.
