I am taking a college course using processing and I have an assignment due tomorrow that is just killing me. Could someone look at my code here and tell me why they think it isn't working?

Much appreciated, thanks:

void setup (){
  size(400,400);
  smooth();
  frameRate(30);
}
    if (mouseX < width/2) {
      draw ();
    background(0,30,200);
    stroke(0);
    fill(30,200,0);
    rect(0,200,400,200);
    fill(240);
    rectMode(CENTER);
    rect(200,175,50,50);
    fill(100);
    rectMode(CORNER);
    rect(183,168,10,10);
    rect(207,168,10,10);
    fill(50,50,0);
    rectMode(CENTER);
    rect(200,194,8,13);
    noStroke();
    fill(255,255,0);
    ellipseMode(CENTER);
    ellipse(75,100,40,40);
    fill(200,0,0);
    triangle(200,130,175,150,225,150);
  }
  else {
    draw();
  background(0);
    stroke(0);
    fill(30,200,0);
    rect(0,200,400,200);
    fill(240);
    rectMode(CENTER);
    rect(200,175,50,50);
    fill(100);
    rectMode(CORNER);
    rect(183,168,10,10);
    rect(207,168,10,10);
    fill(50,50,0);
    rectMode(CENTER);
    rect(200,194,8,13);
    noStroke();
    fill(255,0,0);
    ellipseMode(CENTER);
    ellipse(75,100,40,40);
    fill(200,0,0);
  }
