I only add a garnish of parsley, mint, etc. I've never "chanced" it by adding any other accompaniments. I didn't see anything in the rules of this contest addressing it, but I wouldn't chance an elimination if I were you.
You know what?! I was thinking about the first part of the competition. For this part, they don't even REQUIRE a photo, so IT DOESN"T MATTER!!!! I just came to that revelation when I went back and read the contest rules!
You're safe, Spinklet, whatever you do with the photo in this part of the competition.
