In Java script, I decided to create a house. I was not sure how much I wanted to add to the picture, so I just added the trees and sun to fill some space. My biggest challenge was positioning all 12 shapes to look relatively symmetrical, but this was my outcome.
function setup() {
createCanvas(400, 400);
}
function draw() {
background(255);
background(0, 0, 255, 90);
fill('yellow');
ellipse(350, 80, 65);
fill('green');
rect(0, 350, 400, 70);
fill('white');
square(140, 200, 150,);
fill('red');
triangle(140, 200, 290, 200, 205, 90);
fill(0, 0, 255);
square(160, 250, 25);
square(245, 250, 25);
fill('brown');
stroke('black');
strokeWeight(3);
rect(205, 310, 20, 40);
fill('gray');
rect(205, 350, 20, 50);
fill('brown');
rect(50, 330, 10, 50);
rect(355, 330, 10, 50);
fill('green');
ellipse(360, 320, 50);
ellipse(55, 320, 50);
}
