I myself use the paint with color method, I paint with colour to make sure how I wanted the pose, clothes, hair, and other details to be, and then I draw a rough sketch above it to make it cleaner, and refine the lineart once more And after all of that, color the drawing and finally, shade or highlight the part where you wanna add details I have a video of it in my channel Also! The first sketch is NOT the final product, you dont have to follow the sketch 1 to 1 if you're drawing the lineart, you can always change things if you think something needs to be change I often create too much detail, and then i decide to just not do it in the final lineart, the same goes for reversed scenario
