Don't draw him much.

He's from a kingdom where dragons once existed but were hunted to near extinction. At the same time the mages of the land were also being persecuted and killed. So they came together, and using both their powers claimed the island for their own. After, the mages turned the last three dragons (all males, of air, water, fire) into human men and they had children with the strongest female mages, so their races would forever be one. Those blood lines give rise to mages (humans with mage or dragon magic), dragoons (mostly human with some dragon features), dragoon mages, demis (more dragon features), and at one time there will be three male dragons, one of each element. Dragon bloodlines aren't always expressed at birth though, so throughout a person's life the dragon magic and features may appear and grow as the dragon blood overpowers their human blood. This is what happens to become a full dragon. Tyrrin gets to become the water dragon. Yay him.
