This project was a fun challenge for me because it required a heavy amount of step-by-step variable referencing, but it also encouraged me to think very logically. Every time I set up coordinates, I actively made sure to question if I could use a variable to simplify my code, and this made it significantly easier to randomize the face (as well as other features) later because all of my variables were already consolidated.

I enjoyed getting to play with an abstract art style, and I made my characters reflect that; they each have simplified features, but my program incorporates a wide array of body types and shapes. I’ve come away from this project with a much stronger understanding of how to utilize local and global variables, as well as how to use if-else statements to set up different conditions to ensure my faces didn’t distort in odd ways.
