Actually, this is a char of a friend of mine:  RenaAyama .
It came to my mind when I was taking a break from the color job I'm still occupied with (gah, so few time x.x).
She's called Setsuna but unfortunately she doesn't have something like unique markings so even her creator didn't recognize her. xD
But anyways, it's good to hold a mechanical pencil in hands and get creative again. ^^
