I've decided that I will do yet another tutorial (despite the other not being finished) in which I teach how to transform a healthy looking character into a sickly, unwell looking character. I decided on Yuka Mochida because of my roleplay blog (in which she gets left behind and is still surviving the Elementary School after a few months of getting by).
To start with, draw your character with their typical, lively appearance. Keep this in sketch form as this will allow for changes. I started this in MangaStudio and will be shifting into photoshop to continue the work. Unlike other times, I will not be applying line work until last thing, working mainly on the colour.
