Im pretty shit at explaining things so i’ll use this for basic example. Firstly if you know how shadows work and stuff then it shouldnt be to hard. Otherwise go study that shit.
So you got your flat colors down for the first step
Next lay down a dark tone set to multiply, idk about 70% i guess? up to you
Start adding some shadows set on another multiply, shadows can be however dark. 50-70%
The add your light source, i used color dodge in this one. Dont use super bright color or it will look like blinding light. (again if you know light/shadows shouldnt be to hard)
I add a touch more dark in the shadows for effect…or something like that.
And there you have it, this maybe helpful lesson was brought to you by a potato, chur.
a small glitter tutorial that is badly cropped and vague i am sorry
hopefully this helps some people though!! This tutorial is for clip studio paint or photoshop mostly but im pretty sure you can do it with any program that has particle brushes!
