Although I've never seen (or heard of) Claymore or Priscilla, this is truly a wonderful drawing! I love how the background has a slight light pink hue (and a slight lilac-y lavender-y hue thanks to the pencil marks) in some places, and, gosh! That face! I love the pointy nose and the soft-looking feminine lips. Plus, the eyes! Wow! They're so beautiful and so girly thanks to the eyelashes. This picture is to die for!
All in all, the drawing looks both so soft (thanks to the soft background colours, and the way the face looks so smooth and flawless) yet somehow rough (thanks to the really spiky hair and the way some of the pencil marks look rough) at the same time; I really like that contrast! Great job!
