I drew Shikishi for Fuyukomi (Comic Market 95).
Here is the memo of how I drew it.
1) Firstly, I drew the draft using my PC. Then print it out. Using the hardcopy and a carbon paper, I dopied the sketch on the Shikishi paper.

2) I inked the lines. Since I wanted to re-create what I usually draw in my manga, I consciously enphasized black and white contrast. Painting the beard and the hair takes a while. When I do that digitally, it's just one second process though.

3) At the end, I added color to the background adding my signiture and stamp.

Voila!
