Not quite sure who it is, because it is a bit blurry. But at aa geusse i would say it is Artemis.
Well, some constructive crit.
Because it is blurry, i can't really comment on the eyes, but i think you have got a good style of drawing hair. The chin comes to a harsh stop which gives it thee pointy loook. Keep the point, but make it a little less sharp.
Hope that helps. :D
I know you love one hundreds and thousands
Your Tears don't fall, they crash aroud me
Her conscience calls, the guilty to come home
gotta love Bullet For My Valentine
