This male vampyre is dressed in black with golden details, and like all the other Princes, he is standing on someplace high (probably to represent air since Prince is air). He has roses as embroideries on his cloth and black feathers as well. There is even a raven behind the vampyre, probably to reinforce that this card is air of air. He is holding a white rose with his left hand and a bloody dagger with his right hand. There is a pink gem on his shirt, you have to look really close to see it. He seems full of life, ferocious, he is looking down below and he in a defensive stance, and his quick mind is already thinking about plans, battle plans.
He reminds me of Lestat de Lioncourt in the Anne Rice's vampires books.
The Tarot of Vampyres is inspired by the Thoth Tarot so this card is the Prince of Swords in the Thoth Tarot and the Knight of Swords in the RWS.
