Hi like the title says i need to draw a head nose and mouth in one function. I am still new to processing and i get concfused very easily with all the vars and in doing so i get lost what i want to do. my head function is very basic but i wanna use better code for drawing my head a nose and a mouth. My head function only draws the head i dunno why it's not drawing the mouth and the nose when i call the head function in the void setup. here is my code.

Also i have to Rewrite drawHead() so that it will accept two arguments which specify the position at which the head is drawn then i have to draw the head in three places on the display. Please reply asap. I really need help with this.

void setup() {
  smooth();
  size(500,500);
 
  drawHead(250,350);
  drawHead(400,120); // draws head at specific pos
  drawHead(120,120); // draws head at specific pos
  drawEyes(380, 100);
  drawEyes(100, 100); // draws eyes at specific X .Y pos
}

// Function that draws head with eyes, mouth and nose
void drawHead(int xPos, int yPos) {
  int headSize = 100; // var for the headsize
  int mouthX = 100;   // var for the x pos of the mouth
  int mouthY = 125;   // var for the y pos of the mouth
  int mouthWidth = 100;  // var for the mouth width of the mouth
  int mouthHeight = 40;  // var for the mouth height of the mouth
//  booleon mouthTrue = true;
 
 
 
  fill(255,216,0);        // applies colour to the head
  ellipse(xPos,yPos,headSize,headSize); // position of the head
  line(113,130,125,130);  // position of the first coordinate for the nose
  line(113,130,120,135);  // position of the second coordinate for the nose
  line(120,135,125,130);  // position of the third coordinate for the nose
  noFill();               // applies no fill to the mouth
  arc(mouthX,mouthY,mouthWidth, mouthHeight, PI/6,PI/2 ); // position of the mouse
 
}



void drawEye(int xPos, int yPos, int eyeSize) {
  // set the fill to white
  fill(255);
  // draw the white of the eye
  ellipse(xPos, yPos, eyeSize, eyeSize);

  // set the fill to black
  fill(0);
  // draw the black pupil
  ellipse(xPos, yPos, eyeSize/2, eyeSize/2);
}

void drawEyes(int xPos, int yPos) {
  // specify the size of the eye
  int eyeSize = 20;
 
  // specify the gap between eyes
  // base it on the size to ensure enough space
  int gap = eyeSize*2;
 
  drawEye(xPos, yPos, eyeSize);      // draw the left eye
  drawEye(xPos+gap, yPos, eyeSize);  // draw the right eye
}
