Yup, finally putting together a tutorial after some dozen of months★
Part one is basically from the sketch(?) to masking areas and laying the base colors.
If I really did actual part of lineart-ing, I wouldn't really know what's put but give advices 8D; In brief sentences, use lots of creating new layers and drawing lines overlapping with each others and erasing parts of them and merging them (really brief indeed).
