At first, I had no idea what the yellow thing that kept appearing in the NaviAvatars group logo meant. So I did a screenshot so I could look closely, and discovered that it was a blue emoticon riding the Toruk. A Na'vi emoticon, I mean XD Maybe you should also draw the darker blue stripes the Na'vi have in their skin texture? anyway, I like it ^^
Got this from the wiki page "Leonopteryx, toruk. A large aerial predator, similar to the ikran but much larger, with crests on top and below its beak. Na'vi legend tells of the toruk and that only the 'chosen one of Eywa' will be able to swiftly bond and ride the toruk during times of devastation, leading the Na'vi out of the darkness. It has been said that only five Na'vi have ever managed to bond with the toruk, becoming the revered toruk'makto. The name "toruk" means "last shadow" in the Na'vi language, referring to its obscuring attack from above being the final warning of impending doom."
toruk'makto was her grandfather's grandfather. Leonopteryx is the human name for it.
