AMINE AND MANGA

Naruto (NARUTO—ナルト—, romanized as NARUTO) is an ongoing Japanese manga series written and illustrated by Masashi Kishimoto. The plot tells the story of Naruto Uzumaki, an adolescent ninja who constantly searches for recognition and aspires to become a Hokage, the ninja in his village that is acknowledged as the leader and the strongest of all. The series is based on a one-shot comic by Kishimoto that was published in the August 1997 issue of Akamaru Jump.

Naru Nanao (七尾 奈留, Nanao Naru) (pseudonym) is a female Japanese artist from Okinawa, Japan. Nanao's choice of her pseudonym stems from the Circus' game Aries; one of the characters was named Runa Nanao (七尾 留奈, Nanao Runa). She is a free illustrator and thus is not affiliated with one single company; she is primarily a character designer. She began working with video game developers in 2000, but she is most well known for providing original character design for three heroines in the original D.C.: Da Capo visual novel by Circus released in 2002. Other works include Canvas 2: Niji Iro no Sketch, Ef: A Fairy Tale of the Two., and Sola. At one point, she only went by her given name Naru. She is the supervisor of her dōjinshi circle known as "Ice and Chocolate" (あいすとちょこ, Aisu to Choko^?). She often collaborates with another circle named "Poteneko" (ぽてねこ). She even provided the front-cover illustration for the Comiket 70 catalog for August 2006.

I've got two of her images saved in my art inspiration folder. Afraid that I don't know any more about her than you though, probably less. What doujin circle is she in?

To me it seems that she uses CG for her colouring. The second one you posted looks like it could've been traditional, but that might be due to the graininess/bad quality of the image.
Judging by the two images I've got saved on my hard drive (which are somewhat higher in resolution) I'd say that the inking is traditional though. It's probably individual, but I think you can get that detailed if you're drawing on A3.

Her work is gorgeous, although, after Alichino I've grown rather wary of super detailed, super pretty manga. It would be awesome if that could be combined with a super awesome story, but so far I haven't seen it happen... Maybe you could be the first!
