Watercolor comic sample
Yoshiyuki Sadamoto, although it is watercolor, the texture is really good.
Tomomi Kobayashi, most of her works are game characters, so the colors are rich and the dynamics are natural.
Fujiwara Kaoru, freehand style.
Takehiko Inoue, in his "WATER" & "Ink", there is no need to repeat the human structure and the like. It is obviously very rigorous, but it makes people feel that the picture is free and unrestrained and full of tension.
In Shizi today, the colors of the characters and background are very coordinated, with delicate brushstrokes and rich colors.
Akihiro Yamada, composition, lines, color... You can also learn a lot by copying a few of his paintings.
Naoko Takeuchi, except for those laser-like eyes, her illustrations are always stunning. Texture and airbrush effects will appear more in pictures.
CLAMP, their paintings seem to be a mixture of markers and watercolors.
The paintings of the above people are mostly watercolor manuscripts (it is not clear whether they have been converted to CG now), and the collections of paintings can be found online.
