I love too much, it is really superb, sorry for my english , i'm french ^^
The way you drew the fire and mouth looked like Johns helmet XD
who knows...maybe i inspired them? XD yeah no...really all of us had pretty much draws the inspiration for dragons from dinosaurs.
wyverns being the flat out easiest as they , like pterosaurs have 2 wings and 2 legs.
in my comic dragons when they mature get stronger wings, which enable them to use their front legs as arms and walk on hind legs and wings
definitely gives them a better grip on things xD
Do you even know the game Monster Hunter? If not you should take a look at it! It could be inspirating for you ! :3
