Step 2: Then draw its nose and abdomen with arcs, but do not connect them with another arc.
Step 3: Use two arcs to draw the tail, and connect another arc in the middle.
Step 4: Add two semi-elliptical fins and an arc-shaped belly.
Step 5: Then add the eyes and draw the arced fins on the back.
Step 6: Finally, apply a nice color, and the dolphin is now painted.
