Progress thing

(there is a missing first step which is just the sketch)

-Cleaned out sketch or messy lineart

-base colors (on separate layers)

-simple shading

-merge all layers with the sketch layers and blend the lineart and darken the shading, i usually start with whatever is at the bottom like the skin since the hair will go over it, it wouldn't matter if it's kinda messy

-more painting and adding details 

-a few extra layers for any patterns or highlights 

Im not very good at explaining these sort of things but if you have any questions about this then feel free to ask i'd be more than happy to answer. >u<
