Hi I'm a brazilian designer, a logo specialist. I just could not let your contest pass by :-) Some leaf elements incorporated into the logo so we have the Amazon added to the design. Brazilian flag colors used, and round shapes for movement and happiness.
Another option from Brazil for you. Here, the happy style of life of brazilians communicated through the moving letters. A strong icon, brandable, so you can use in tags or whereever you may need to create a better customer experience. The graphic was also based on the inner part of our flag.
