final effect
1. First use the pen tool to draw a rough shape.
2. Follow the steps above to draw the outline of the human body with a pen.
3. Overall coloring. Fill each part with the approximate color.
4. Use the Burn/Reduce tool to add some highlights and shadows.
5. Continue to use the deepen/reduce tool to outline the facial features. Gently swipe the applicator tool over the hair.
6. Use the pen tool (without simulating pressure) to trace the eyeliner, and use the same method to trace the eyebrows.
7. Use the burn/reduce tool to boldly paint on the face of the character. For the hair, I directly used the brush and painted it with several colors to create highlight shadows. Then use the smudge tool with a smaller value to sweep over the hair.
8. Hair is the most troublesome. Every time you draw hair, you need several layers. Here I first draw a relatively long path as the bottom layer of the hair, and then simulate the pressure stroke (this step requires separating two layers to do two times), the whole thing is blurred after the second stroke, and the value is 1-2. This will look thick.
