Relay For Life Facebook Covers (Theme: One World, One Cure)

There was a request from a request from a Relay with the theme "One World, One Cure" and I thought it sounded like a pretty cool theme that other relays might use so instead of just using a cover I already completed I decided to design a couple to choose from. Below is what I came up with, but if you have ideas that would fit with the theme drop me a comment.
