In general, i draw while referencing the art id like to emulate, which is the 2000s moe/visual novel style. I study aspects of the art i'd want in my work, things from highlights to eye shape to hands. What ill do is draw A LOT throughout the day, spanning months, till i gain muscle memory, and have a good understanding of what i want to draw and how to do so. I had to switch from doodling in autopilot mode in my comfort zone to trying out new styles i like while making the effort to really think about what im doing and why, basically.
Over the past months, ive had to work on making my lines neater, anatomy reasonably correct, and figure out the basics of lighting. Think of basic shapes with different kinds of lighting over them (cylinders, rectangles, cones, etc) and combine those forms to be able to shade more complex shapes.
As for that chibi doodle style, i keep the head large and add minimal folds to clothing, maybe some highlights if needed to the hair as well. I se both regular and beady eyes, whichever i feel like drawing. To scribble in that blue ink, i sketched very lightly with a blue bic pen, putting more pressure where darker blues would go
