I've always loved playing cards, and am fascinated by the beautiful, intricate illustrations. Not only are they fun to look at, but playing cards are also a great example of exceptional usability design. Designshack has a pretty comprehensive overview, if you want to learn more.
Lately I have been trying to focus my personal illustration projects with a design centered approach. I wanted to explore symmetry, unique shapes, and geometry while maintaining a fun and whimsical vibe. I used a relatively limited color palette and employed geometric shapes and pattern to add visual interest.
Hope you enjoy!
