Dlib + OpenCV Draw Points Landsmark

I would like to draw contour of the cheek, as in the image below:

I am using OpenCV and Dlib to detect the landmarks, And I do not know how to manipulate the Dlib points. Does anyone know how I can make the contour on the cheek?

Here is my code:

import cv2
import dlib
import numpy as np


def imprimePontos (imagem, pontosFaciais):
for p in pontosFaciais.parts():
cv2.circle(imagem, (p.x, p.y), 2, (0, 255,0) ,4)

def imprimeNumeros (imagem, pontosFaciais):
for i, p in enumerate (pontosFaciais.parts()):
cv2.putText(imagem, str(i), (p.x, p.y), fonte, .55, (0, 0, 255),1)

def points (imagem, pontosFaciais): #here where a draw de points
p68 =[[15, 47, False],
[47, 28, False],
[28, 30, False],
[30, 12, False]]

for k in range(0, len(p68)):
pontos =
for i in range(p68[k] [0], p68[k][1] + 1):
ponto = [pontosFaciais.part(i).x, pontosFaciais.part(i).y]
pontos.append(ponto)
pontos = np.array(pontos, dtype=np.int32)
cv2.polylines(imagem, [pontos], p68 [k][2], (255, 0, 0), 2)

fonte = cv2.FONT_HERSHEY_COMPLEX_SMALL
imagem = cv2.imread('1.jpg')
detectorface = dlib.get_frontal_face_detector()
detectorpontosfaciais =
dlib.shape_predictor("shape_predictor_68_face_landmarks.dat")
facesDetectadas = detectorface(imagem, 2)

for face in facesDetectadas:
pontos = detectorpontosfaciais(imagem, face)
print(pontos.parts())
#imprimePontos(imagem, pontos)
#imprimeNumeros(imagem, pontos)
points(imagem, pontos)


cv2.imshow("Bucheca", imagem)
cv2.waitKey()
cv2.destroyAllWindows()
