I've posted a similar article before where Masakazu Katsura displayed his artistic prowess on how Zetman is drawn. This time it's Yoshitaka Abe, popularly known for his work on Serial Experiments Lain, showing as how pros work on web manga.
The work is for Ryoshka Ryoshka serialized by Square Enix Ganga, I haven't heard of the story before so I'm new to the characters. Nonetheless it's another manga powered by moe-lolis! as seen in the clips so you might be interested if you 're into it.
Anyway here's the full video of how Ryoshka Ryoshka is made from the bare bones of line work to it's charismatic coloring.

The only thing that is missing now is an in depth video of how anime is made. Hope I can find some good video published by one of the popular animation studios in Japan in the future.
