For the "National Parks" contest, I focused on the national parks in California. I was originally going to make some kind of ornate badge or patch for each park, but decided I didn't have enough time for that. Instead I focused on a typographical approach. I started off using just the colors in the National Park Service logo, but that turned out too dull so I added more greens, blues, and grays, until each of the eight hexes had a distinct color.
The texture is the ivy vine from this design. This actually did decently and made it into the top third of designs. My favorite was the entry that had unique bottlecaps for all FIFTY-NINE national parks!
