Draw a good picture of girls:

The following is the hand-drawn process. The first step is to draw a Q version of the couple's line draft on paper:

Step 2, color the line draft:

Step 3, clip the front fabric of girls' T-shirts on the drawing board, and pay attention to the fact that the fabric needs to be laid flat on the drawing board:

Then, draw a line sketch of the girl pattern on the canvas with a pencil, and pay attention to the light when drawing the line sketch:

When the line drawing is finished, you can color it. Dip the brush in acrylic paint and start painting on the canvas. Just pay attention to the plane painting and draw the hair and eyes of the little doll:

Paint the color of the starting clip and skirt:

Then draw the color of the skin:

Then draw the color of the body and write "520" on the clothes:

Then tick with black pigment:

Check all contours:

Next, draw boys. Similarly, clip the boy's T-shirt on the drawing board, tick the lines and start coloring:

The first step, I think the color of boys' hair is too dark, so I added white on the basis of orange and redrawn the hair color:

Draw the color tick and you're done!
