I realize that I'm terribly late here but, wonderful art. The lighting is very well done and I LOVE vivid colors. Not to mention that I'm a fan of the character (obviously). I am in awe at the amount of details you put in here! The shuriken's handle/rope, characters, and stitching (among other things). The background (once again) the amazing details, make this an undisputable top-tier fanart.
I'm in love with this artwork, it's /very/ rare for me to come across an image with such great amounts of detail, the ideal colors, high quality artworm, lighting, and so on. And you don't have to take my word for it, but I've collected approx. 15,000 images of this anime, so I definitely know what I'm talking about.
Normally, I don't reply or comment on fanart. But this is such an exceptional case that I couldn't help myself. 5 stars!
