ah yes I know the author of that fan art, we talk ocasionally. She has a nice gallery and I have a few of her artworks in my videogame collection.
I don't know so many fans can't conceive drawing Maria without the company of Alucard, practically drooling all over him and kissing the land where he walks. Lucky for her she's just a fictional character because between Sotn's "good ending" with her going after Alucard whom she barely knows, the radio drama featuring a rather air headed, helpless version of her, Castlevania Judgment and the fans' pairings I'm afraid the poor girl has run out of dignity xD
I would prefer to see more fan art of her being cool using her magic, fighting vampires and stuff rather than her going drama queen over Alucard. 17 year old Maria seems to act more and more like a damsel in distress when she's supposed to be a vampire huntress.
