The Asian dragon is a water god and is generally benevolent, as opposed to the generally demonic Western dragon. Given that, I don't mind drawings that give them a more playful pose/expression like that Perth Mint one. But man, the colors on that one just ruin it for me. Way too gaudy. That said, I do agree with you that a more ferocious image is better. Well, maybe not terrifying, but more awe-inspiring anyway.

That hydra coin is cool!
