I'm unfamiliar with Kaoru Mori's work, but this video series of her drawing a character from her manga Otoyomegatari is really inspiring. It looks like her pencils are pretty tight with quite a lot of detail, but just in inking this face section she puts in even more detail like the dangling things off the ear rings and the shading in the pupils. I have a feeling I'm going to be watching this over and over again.

The rest of the series is over at this site. It's all in Japanese, but they've embeded the entire series. Really good watch if you're interested in learning how to ink with a dip pen.
