This image is very, very, very, very, very, very, very, very, very (okay...maybe cut the last few 'very's...) old. That is how big I used to draw eyes. Y'see, I started out drawing people from following anime/manga online web tutorials. I remember I couldn't even draw stick people then. Erm, anyway, the dragon is wingless and terrestrial (although it can meld into the ground seamlessly as if it were water, its not advisable to do that while you have a mortal riding you). The dragon's armor is inspired by eggshells. They seem to crack in interesting ways. I've mixed this eggshell effect with the aged-bark effect on the Eldris image to cook up what Flak looks like now. If I were to write a fiction about Terrestrial dragons, I would say something like: 'They hatch directly from and of their eggs, taking their eggshell fragments into themselves, which harden as they age.' What's the girl doing? Gathering herbs, etc.
