First step
First, we draw an inverted triangle cup body, and then draw a "V" shaped arc at the bottom of the cup body to highlight the thickness of the cup. Then we draw a coaster that looks like an inverted "T" shape. Then draw a straw in the cup.

Second step
CupAfter the cup is roughly drawn, we draw a cut lemon on the upper right corner of the cup rim, then draw the liquid surface of the juice inside the cup body, and then draw a cube of ice inside, so that our juice is basically drawn. Finally, we drew and colored the water droplets splashed by the ice cube when it was put into the juice, and the water droplets dripping from the cup. A glass of colored juice is enough to draw.
