Artist's commentary
Responding to appeal,
I liked your idea of Hunikin, a friend of mine, in "an illustration based on a seasonal theme," I've wanted a picture of Hunikin in a Yukata for like a fall festival. I will leave design and color scheme of the clothes, I prefer her hair long and down, but you can also keep the twin tails if you feel that is better suited for your design.
I will be providing the picture to Hunikin on delivery, as well as tweeting it out.
