In order to make the designs more fun and bold, I decided to make the smaller-size cup another color-scheme. Since the large cup matched the top-half of the menu card, I made the smaller cup the same colors as the bottom-half, in order to create consistency across the branding.
Playing around with the lines wrapping around the cup, I also discovered that I liked these looser, more free lines better. I didn't want my design to become too streamlined.
