Felt obliged to review this one.
Even though it's on first sight a pretty ordinary drawing, but then.. The colour of the hair and the gaze seemed oddly familiar and the the title, yeah... This is from Elfen Lied. One of the best and yet ugliest mangas I've ever read.
I read elfen Lied when I was 12, IMO too young for it, but nvm that, when I first read it, the 'dark' Lucy fascinated me. The 'Nyu'-Lucy was annoying and the (I believe there was a) other one didn't seem that interesting. The only differences between those two/three was the look on their faces.
Now to what you have drawn here. It's the expression that makes this Lucy the Lucy she is. As for the hair colour, I think that you could have used a lighter red, or more different colours red, but other than that, very good job, also that you have made the hair fall over one and a half eye.
I do think however that her face itself looks too unnatural. This is not quite how she looked at the world. It's hard for me to explain, but I hope you know what I mean.
Anyways, I still believe you've done a fantastic job here and I'm going to give you an 8/10 and so a 4/5.
