"Blood Immortals": Vincent and Magdalena

Concept sketch for my vampire story, "Blood Immortals". Magdalena was a witch who was dying of old age, even though her dark magic helped her slowed down her aging process. Vincent came to her with an offer of immortality, power, and eternal beauty. She accepted his offer. Though she could no longer practiced magic, her strong magical bloodline allowed Magdalena and Vincent to have powerful vampire offspring that are faster and stronger than the normal vampire.
