What you need to do

Create an image of a cloud composed of three or more circles/ellipses and group them together into a compound shape. Ensure the whole group moves when you change the position variables.
Take the face you drew in Drawing Shapes and group all the sub-shapes together so you can move the entire face by changing the x and y variables.
Advanced (Optional): Create a function to draw the face and another to draw the clouds.

# Compound Shapes

"""
- Draw a tree (rectangle and circle)
- Abstract the position into x and y variables
- Make group position relative to the position variables
