Voldemort's Mistress

I have this really creepy obsession with trying to portray Voldemort as something closer to human.  Already I have Sorina Riddle (her poorly done drawing can be seen in my gallery, still, and it is also one of my featured works) and now I give you the currenly un-named Mistress of Voldemort.
My friend says her eyes look too kind. And her hands are a little small, but...she has hands. It took me several tries to get just the right hands. Her head is a little too big for her body, but meh -shrugs- not much I can do about it now.

I almost called her "Rebecca" but for some reason, it didn't fit.
Oh, that black blob on her arm? That's supposed to be a Dark Mark >.> I wasn't sure what a DM looked like, so I just guessed. If anyone here has some reference images they'd like to share, or some detailed descriptions, to correct this unsightly blob, please share them! I have an outline of her done in pencil, which can be quickly altered.

Which reminds me...
This is the photocopied image, coloured in.
Oh, and that bit on the top about Voldemort being framed?
-coughs-
I see a Voldemort-related fan-fic rolling out at some point.

[Edit]
"Each Death Eater bore a sign, the Dark Mark, a skull with a serpent protruding from its mouth like a tongue, burned into his or her left inner forearm by the "Dark Lord"; when they had killed, Death Eaters would send the same sign into the air, comprised of emerald stars blazing in a haze of greenish smoke, causing terror when it was seen."

Nevermind. >.>
I found out where the burn should go...technically, she shouldn't be brandishing it at all. It would be hidden under her abnormally long gloves. -scuttles off to erase error-
You lot will have to make do with this one.
By the way, she has a name now.
"Mararose Briann Longly" is her birthname. Like Voldemort, she's taken on a stage name, if you will. And that would be "Nex"
