Draw a Self Portrait
Problem Statement:
The pre-placed blocks will draw the ellipse to provide the shape of the face. Add more blocks to draw a self portrait. Use different fill color blocks to change the colors of different features.

// radius determines size of circle

// angle here for part of nose and mouth
// is the bottom part of the circle
// so angle is different from eyebrows
