This is the sort of mood you never want to see Hueroc in. Pissed off, roaring in challenge, violent, and probably moments from attacking whoever's responsible for setting off his temper. Maybe he was insulted; maybe another dragon is challenging for his territory; maybe his mate and the eggs have been threatened. But no matter what the circumstances, the best advice is to flee quickly--or face the consequences.

This is a very good sketch commission I bought from the FA user Ryoken, and you can find (and fave) it in his gallery here.
