My second Sketch

function setup() {

  createCanvas(400, 400,);

  background(1);

  for(let i=0; i<1000; i++){

    stroke(random(200),random(100),random(210));

    line(random(width),random(height),random(width), random(height));

  }

  noStroke()

  fill(200,10,0,100);

  for(let i=0; i<1500; i++){

    let x=random(width)

    let y=random(height)

    let diameter=y/24

    ellipse(x, y, diameter,diameter);

    }

  fill(30,40,200,100);

  for(let i=0; i<1000; i++){

    let x=random(width)

    let y=random(height)

    let diameter=22/y

    ellipse(x, y, diameter,diameter);
