Aztec Wrym Project

I was tasked to create a creature/character/environment for one of a few civilisations. Aztecs was one of the options! I wanted to create a tameable creature that the Aztecs could use to manoeuvre around the forests. I went with a few ideas but they looked too bulky, aggressive or not agile enough to dodge through trees while flying through jungles.
I came to conclusion of a serpent like figure, no legs and wyvern like wings to slither and drag itself through the jungle floors would be ideal and more of a rounded head to make it look a little more approachable.
This project was done on my iPad and, unfortunately, Nomad doesn't have any tools to add hair to the 3D head.
