I can just hear her saying, "Arrrr. Your booty shivers me timbers!" :D
the body stance gives it motion in freeze frame; that's not easy to do. The hat's angle is a bit off (skull) and the blood on the sword looks more gelatinous than bloody. and while i've got the critical momentum, the eye looks misplace on the face with the mouth; her emotions are mixed.
Shift the skull a bit so it's in line with her head and look at some pictures of blood on weaponry to get the best effect of blood. work a bit with her eye and other general emotions to get something working with the pic.
as it stands, I'd give it a 4, solely on those things upstairs. Fix them and I'll fiven it for sure!
great job,i love how you did her legs.
but the sword and the hat made not so well...
wow, beautiful piece of pixels! Sail away with meeeeeeeee.. ;)
