I like how the light purple shading crowns her hair.
The purple and how it's shaded reminds me of how people look while under the blankets. Like, you know, the whole 'I got a secret. Let's hide under the blankets at a sleepover and tell it!' sort of deal. Yet, I doubt Hana would care much for the whole sleepover or secretive sort of deal, but it's a fun imagery. Perhaps Honor (spell check?) and her are having a sleep over under the blankets or something.
Besides the possible setting, I like the skin tone and how on the right side it almost blends into the purple background. It makes the image look pleasant and very warm (intimate as well). The one thing I like most about Hana is her eyes and how they're usually lidded like bedroom eyes. It makes it hard to be able to judge her for the person she is on the inside, her intentions, and motives. I'm sure it drives people crazy, but it makes me wonder, with her eyes so collected and mysterious, what pain or problems she may hide behind those beautiful eyes?
