Regardless of copyright or trademark, any art you see in any of my cards started as stock photography, generally on clip art or sites such as istock. I believe that's where these gators came from. Then I run them thru the paint program on my computer, as well as at least 1 or 2 different photo manipulation sites, such as Picnik or Befunky.
Glad you liked it, btw
I'll see if I can't come up with something for any of the other marks, if that's cool.
