This tutorial is quite innovative, converting some daily photos into beautiful vector images. The effect is very good, but it requires strong art and PS skills. Those who are interested can try it.
Original picture
final effect
1. Open the original image material and slightly liquefy it to adjust the face shape and body shape. Since everything has to be drawn, skin resurfacing and other things can be dispensed with.
2. Adjust the color you like, preferably a brighter one, as it will look better this way.
3. Use the middle color of each part to select a rough outline. For the hair, use the gradient overlay in the blending options, which is more natural. I will make hair, face, body, clothes, pants, etc.
4. Color the shadow part with a dark color, using one color. Use a pen to outline more details, paint the larger area first, and then change the transparency of each fill layer to 30-70.
