Sometimes called the 'fin-head', the Istarian Frilled breed of dragon is named for its ear frills. These frills are expressive and often give away the dragon's mood in body language.
I have another version of this sprite that shows the same forshortening in the head as the outstretched arm, but I think I kinda suck at forshortening and the head came out looking just a bit too big. I may use it anyway, haven't fully decided yet.
Bronze is more for the personality than the appearance... I'm just not nosy enough for gold and as for silver... I hate the cold, lol. For physical characteristics I'd have to go with red.
