Dragon designs and behavior

Dragons I did during and after Brynn Metheny's workshop on Creature Design & Animal Behavior. I did learn a lot during this workshop, and I tried to apply it with the pitches she gave us.
I also tried to give them kind of species name, while keeping in mind that dragons would be older, discovery-wise, than dinosaurs, so I kept it in ancient greece and tried to link words as best as I could.
