Hi - here's a version of the design with the cactus reversed out to white.
It's bad what happened in your contest with one designer copying the design of another, but I wanted to let you know that if you open the contest up again new designs I'm sure you'll end up with a design you really like - I think it's a shame to let all the hard work by you and the designers go to waste because of one designer that decided to take a shortcut.
