I made this rough sketch for the two remaining members of the "Seven deadly sins" Vamprie Family. Though this is just my idea, I'll be glad if SP approve this.
Lustful Vampire Dragon
The Lustful Vampire Dragon is a real masochist. Its angle-like wings can attracts so many dragons and it will ask them to fight. It will enjoy every attack and keep alive just so it can fulfill its lust.

Sloth Vampire Dragon
Sloth Vampire Dragon is the laziest of all Vampire Family. It doesn't like wasting time for other activities. It will fight as fast as possible so it can back to slumber.
Special Skills: Leech Fangs (Dream). Steals life points from opponent's. CD skill: 3 Turns. Quick Victory (Wind). Always dealt critical to any elements. CD skills: 4 turns.
