Disclaimer: I did this for my helpers to follow my style and do it with the most used lighting condition I handle for my manga. So it doesn't cover everything there is to be known in lighting, nor is it the most accurate. (in fact I just want believably to my eyes.)
Edit: added another section at the end.
Edit2: 1-wrong way to do it, I just simply didn't do it wrong enough. XD This tutorial done for my E-Depth manga/anime project

I noticed a lot of people can "cell shade" and there is a lot of cell shade tutorials!
But there's almost zero tutorial on various lighting direction and how it affects shape of the shadows. (and I thought photographs would help, but no.)
At least my style/anime is formulated enough, i can make a template set for people. (especially my helpers)
I'm doing a series of this...!
