This is amazingly gorgeous! It looks right out of my favourite card game Magic: The Gathering! Maybe you could consider getting work from them haha ;)
I don't know why but I really like the original one of the vampire biting her leg. The vampire had a certain sense of sorrow to his eyes as if he doesn't want to feed on her blood but he needed to while the woman was in pain but looked confident that what she was doing was the right thing.
Good stuff!
